Program understanding can be enhanced using reverse engineering technologies. The understanding process is heavily dependent on both individuals and their specific cognitive abilities, and on the set of facilities provided by the program understanding environment. Unfortunately, most reverse engineering tools provide a fixed palette of extraction, selection, and organization techniques. This paper describes a programmable approach to reverse engineering. The approach uses a scripting language that enables users to write their own routines for common reverse engineering activities, such as graph layout, metrics, and subsystem decomposition, thereby extending the capabilities of the reverse engineering toolset to better suit their needs. A programmable environment supported by this approach subsumes existing reverse engineering systems by being able to simulate facets of each one.

Reverse engineering is when a real part is analysed in detail in order to create a numerical or virtual model. Reverse engineering allows for multiple redesign possibilities, including changes in the material, the shape and the parameters of the part. Reverse engineering is mostly a manual activity for companies and is thus time consuming. Indeed, measurements must be done in scanned files in order to fit sketches on a mesh and to finally rebuild the computer-aided design/bill of material. This manual process is acceptable when reverse engineering is exceptional. But it is considered as a non-value task when reverse engineering is routine. This non-value task could be automated, at least partially. To make it possible, a capitalization of the company’s part catalogue is a necessary step to proceed. The use of this capitalization can then drive the reverse engineering tasks to enable faster redesign possibilities. The aim of this contribution is thus to propose a knowledge model to support reverse engineering activities in order to integrate the reversed parts quickly into the new product’s detailed design. An extended knowledge framework based on the core product model is proposed, and a use case is shown to validate the feasibility of the proposal of the reverse engineering methodology called PHENIX.

The e-assessment, as an important part of any e-learning system, faces the same challenges and problems such as problems related to portability, reusability, adaptability, integration and interoperability. Therefore, we need an approach aiming to generate a general process of the e-assessment. The present study consists of the development of a generic e-assessment process which should be adapted to any learner profile. This e-assessment process is implemented as a composite cloud service which could be invoked by any existing LMS regardless of its environment.

The growing emphasis on information for the development of products, services, and managing activities has increased the need for the integration of data which has been collected and used for various IS applications. Problems arise from the integration of information from such a variety of sources. One approach to this problem is reverse engineer these systems. Reverse engineering derives a data model from existing sys-tems with the aim of redesigning it. The paper describes a data modeling approach that takes data from general journal and an archetypal specialized journal and translates it into an entity-relationship diagram. The article also discusses areas for future research.

Reverse Engineering (RE) can be interpreted as procedures and processes in dismantling an object to find out the materials, working methods, or technology used so that the object can function properly. Design activities using the reverse engineering concept make it easier for students to understand product specifications, product advantages and disadvantages, product production processes and production cost estimates before designing new products. The laboratory is one place that can be used to carry out the reverse engineering process. The bulkhead reactor is an alternative to the stirred tank reactor with the aim that the resulting product is maximized both in terms of quantity and morphology or shape of the material. The benefit of disassembling this product is as a first step in understanding the concept of reverse engineering in the task of designing machines or tools. From the results of the study, it was found that the formation of struvite occurred at pH 9 using an air flow rate of 1 l/minute.

To better understand and exploit the knowledge necessary to comprehend and evolve an existing system, different models can be extracted from it. Models represent the extracted information at various abstraction levels, and are useful to document, maintain, and reengineer the system. The Knowledge Discovery Metamodel (KDM) has been defined by the object management group as a meta-model supporting a large share of reverse engineering activities. Its specification has also been adopted by the ISO in 2012. This paper explores and describes alternative meta-models proposed in the literature to support reverse engineering, program comprehension, and software evolution activities. We focus on the similarity and differences of the alternative meta-models with KDM, trying to understand the potentials of reciprocal information interchange. We describe KDM and other five meta-models, plus their extensions available in the literature and their diffusion in the reverse engineering community. We also investigate the approaches using KDM and the five meta-models. In the paper, we underline the limited reuse of models for reverse engineering, and identify potential directions for future related research, to enhance the existing models and ease the exchange of information among them.

Reverse engineering process has been demonstrated to be reliable solution in solving problems regarding missing information and/or details referred to the functional areas of parts. Based on the specific activities of the chain of processes that defines the reverse engineering concept it can be collected essential information in order to reconstitute important zones of broken parts. The present paper describes an approach that was used to recover a plastic gear part. The case study provided a moulded injected plastic part that was broken during the normal function. The entire process supposed scanning the toothed area that remained and rebuild the contour that was used in CAM software as input data and especially the machining strategy used to perform both sides of the part. The machining process was employed on a CNC graving machine tool.

Full textAbstract:
Educational Reverse Engineering Activities referred to as the acronym -EREA- help engineering design students to: Acquire and develop a set of abilities that raise their awareness of the design process; expand their sources of inspiration, position their actions within the lifecycle of a product, and transform theoretical knowledge into practice. However, it was detected that although such activities sparked interest among engineering design educators, they were either absent from typical engineering design curricula or were not fully exploited.
After analysing the causes for it and determining that the creation of a collection of resources for the study of educational reverse engineering activities was the best way to reach a geographically dispersed community and thus start trying to change the existing research situation, the development of such resources began with the goal to address as many of the concerns as possible found whenever trying to implement EREA into existing engineering design curricula.
The contents selected for inclusion in the collection of resources then, were derived based on initial exploratory discussions with experts in academia and industry; from the feedback received from peer reviewed conference papers stemming from this doctoral research, and from the presentation of intermediate results to early reviewers of this project; for such reasons, the information presented in the different resources targets first time (or novice) instructors of reverse engineering activities and takes into account not only the technical but also the pedagogical and administrative considerations implicated in the study of academic activities, and their potential introduction into an existing engineering design curriculum
Given that some relevant information about the topic already existed but it was dispersed across different areas of knowledge; rather than developing all topics from scratch again, a conscious effort was made to examine published literature and to consult with domain experts to integrate and contextualise all existing information into a coherent body that could be complemented with the original results originating from this project.
The major sections comprising the collection of resources then, are listed below:
- Resource 1: Fundamentals of Educational Reverse Engineering Activities
- Resource 2: Reverse Engineering and Learning
- Resource 3: Misconceptions about Reverse Engineering
- Resource 4: Benefits of Reverse Engineering
- Resource 5: A Proposed Methodology for Reverse Engineering Analysis in Engineering Design Education
- Resource 6: A Suggested Pedagogy for the Teaching of Educational Reverse Engineering Activities
- Resource 7: Integrated Example of an Educational Reverse Engineering Activity on a Disposable Camera
- Resource 8: Conclusions and Final Remarks
- Resource 9: Miscellaneous Resources for the Study of Reverse Engineering
The abovementioned resources were of a self-contained nature, could be read either individually or sequentially, and were written using the "DRM" framework for research in the area of engineering design. Once finished, a number of academic institutions were contacted to measure their interest in the resources, and in the end 12 different ones in the United Kingdom, Ireland, France, Denmark and Germany showed their interest in the research project and agreed to receive the document for reading, thus helping fulfil one of the main goals of this research which was to disseminate the results from it. Other results from this project include five peer reviewed conference papers and a report presented at the Technical University of Ilmenau in Germany after spending a visiting internship abroad to learn about similar approaches to the research into reverse engineering by other schools and traditions of designLas actividades educativas de ingeniería inversa “AEII” tambien conocidas como “EREA” por su acrónimo en inglés ayudan a los estudiantes de ingeniería de diseño a: Adquirir y desarrollar un conjunto de habilidades que elevan su conocimiento del proceso de diseño; tambien a expandir sus fuentes de inspiración, a situar sus acciones dentro del ciclo de vida de un producto, y a transformar conocimiento teórico en practico. Sin embargo, se detectó que a pesar de que tales actividades despertaban el interés de los profesores del área de ingeniería de diseño ellas estaban o ausentes de sus típicos programas de estudio o no explotadas en su totalidad Después de analizar las causas de ello y determinar que la creación de una colección de recursos para el estudio de las actividades educativas de ingeniería inversa era la mejor forma de acceder a un grupo geográficamente disperso y así intentar cambiar la situación de investigación existente, el desarrollo de tales recursos empezó con la meta de atender tantas inquietudes como fueran posible, de aquellas encontradas siempre que se intentaba implementar “AEII” en programas existentes de ingeniería de diseño Los contenidos seleccionados para formar parte de la colección de recursos, fueron definidos en base a conversaciones iniciales de exploración con expertos en la academia y la industria; en base a la retroalimentación recibida de los artículos presentados en conferencia procedentes de esta investigación doctoral, y de la presentación de resultados intermedios a los revisores preliminares de este proyecto; por tales razones, la información presentada en los diferentes recursos está dirigidas a instructores principiantes de actividades de ingeniería inversa y toma en cuenta no solo las consideraciones técnicas sino también las pedagógicas y administrativas involucradas en el estudio de actividades académicas y su potencial incorporación a un programa existente en ingeniería de diseño Dado que cierta información relevante al tema de investigación ya existía pero estaba dispersa entre varias áreas del conocimiento; en vez de desarrollar todos los temas desde cero nuevamente, se realizó un esfuerzo consciente para examinar la literatura existente y consultar con expertos en el tema, para así integrar y contextualizar toda la información disponible en un estudio coherente que pudiera ser complementado con los resultados originales producidos por esta investigación. Las secciones principales que comprenden la colección de recursos se enumeran a continuación: • Recurso 1: Fundamentos de las Actividades Educativas de Ingeniería Inversa • Recurso 2: Ingeniería Inversa y Aprendizaje • Recurso 3: Interpretaciones Equívocas acerca de la Ingeniería Inversa • Recurso 4: Beneficios de la Ingeniería Inversa • Recurso 5: Una Propuesta de Metodología para Utilizar Análisis de Ingeniería Inversa en la Enseñanza de la Ingeniería de Diseño • Recurso 6: Una Propuesta de Pedagogía para la Enseñanza de Actividades Educativas de Ingeniería Inversa • Recurso 7: Ejemplo de una Actividad Educativa de Ingeniería Inversa en una Cámara Desechable • Recurso 8: Conclusiones y Apuntes Finales • Recurso 9: Recursos Diversos para el Estudio de la Ingeniería Inversa Los recursos fueron escritos utilizando la metodología “DRM” para la investigación en el área de ingeniería de diseño y se contactó a diversas instituciones académicas para saber de su interés en tales recursos, al final 12 instituciones en el Reino Unido; Irlanda, Francia, Dinamarca y Alemania mostraron su interés en el proyecto y accedieron a recibir el documento, ayudando así a cumplir una de las metas principales de esta investigación que fue difundir sus resultados entre estudiosos de la ingenierÍa inversa educativa. Tambien como resultado final de esta investigacion se pueden contar 5 artículos presentados en conferencia y el reporte de trabajo de la estancia de investigación en el extranjero.

Full textAbstract:
La transition numérique dans l’industrie manufacturière se caractérise par un passif de trois voire quatre décennies. Certains modèles 3D ou maquettes numériques accumulés durant cette période sont des solides morts, c’est-à-dire des modèles 3D dépourvus d’arbre de construction, qui se caractérisent par des géométries absentes, dû aux changements des logiciels ou à des versions de formats 3D qui n’ont pas subi de mise à jour. Des activités de rétro-conception des modèles 3D, visent à obtenir des modèles 3D sémantiquement riches, c’est-à-dire paramétriques et modifiables, constitués d’opérations de constructions, porteur d’attributs et de métadonnées, avec des règles et contraintes géométriques, etc., grâce à l’utilisation des outils d’ingénierie comme CATIA par exemple ou par des approches à base de nuages de points provenant d’une numérisation par exemple. Mais ce n’est toujours pas satisfaisant, car à l’issue de l’opération de rétro-conception, nous retrouvons souvent un solide avec une représentation sémantique faible ou un arbre de construction absent. Ce qui nous amène à proposer dans le cadre de ce travail de thèse, une méthodologie de gestion des informations liées aux modèles 3D afin d’intégrer à ces modèles 3D des informations expertes que nous qualifions de sémantique. Les solides morts manipulés sont généralement au format de bas niveau tels que STL, IGES ou STEP AP203. Ils sont utilisés comme données d’entrée pour notre méthodologie et ils peuvent aussi être associés à des données de définition du produit, telles qu’une mise en plan du produit ou des documents. Le traitement des modèles 3D exige une solution qui soit capable de gérer d’une part, les maquettes numériques et les informations qu’elles pourraient éventuellement intégrer et d’autre part, l’incomplétude de certains modèles 3D qui est liée au format 3D ou à la limite de la technologie utilisée pour obtenir le modèle 3D (ex : limite logiciel, format 3D de représentation géométrique uniquement et qui ne supporte pas une représentation de l’arbre de construction ou bien qui ne peut pas représenter graphiquement des dimensions géométriques et des tolérances, etc.). Enfin, la pertinence des informations intégrées au modèle 3D, de nature non géométrique, lors de la phase de recouvrement sémantique devrait permettre, dans certains cas, de produire des modèles 3D paramétrés, propres à l’activité du domaine d’application. L’état de l’art, portant sur la représentation des informations contenues dans un modèle CAO et sur la gestion de ces informations, permet d’identifier les techniques et approches qui aident à l’enrichissement sémantique des modèles 3D à des niveaux de granularités diverses. Cette thèse propose une méthodologie nommée Vaquero For CAD Semantic Enrichment (VFCSE) et qui se décompose en trois étapes : l’accès, l’identification et l’annotation. Le but de cette méthodologie est d’intégrer aux solides morts des informations manquantes et standardisées, de nature non géométrique, comme par exemple des spécifications de produit, des tolérancements, des dimensions géométriques, etc. Ces informations seront issues des besoins de l’utilisateur intervenant sur le modèle 3D et proviendront d’un standard sémantiquement riche afin d’être utiles à de nombreuses opérations liées au cycle de vie du produit. Cet enrichissement grâce à ce standard sémantiquement riche, permettra une pérennisation des informations et une réutilisation efficace des informations du modèle 3D. Pour cela, un modèle 3D est récupéré dans un PDM (Product Data Management) grâce à une requête utilisateur. Il est visualisé dans une visionneuse 3D supportant le format STL, IGES et STEP AP203. Ensuite, suit une étape d’identification des composants du modèle 3D. Ces composants peuvent être des pièces ou des assemblages. Aux composants identifiés, est affectée une annotation métier liée à l’usage, basée sur le format STEP AP242 qui représente le standard sémantiquement richeThe digital transition in the manufacturing industry is characterised by a three or even four-decade liability. Some CAO models or digital mock-ups accumulated du ring this period are frozen, i.e. 3D models without a construction tree, which are characterised by missing geometries, due to software changes or versions of 3D formats that have not been updated Reverse engineering activities of CAO models, aiming at obtaining semantically rich 3D models, i.e. parametric and modifiable, made up of construction operations, carrying attributes and metadata, with geometric ru les and constraints, etc., thanks to the use of engineering tools such as CATIA for example, or by approaches based on point clouds coming from a scan for example. But, this is still not satisfactory, because at the end of the reverse engineering activities, we often obtain a solid with a weak semantic representation or an absent construction tree. This leads us to propose in the framework of this thesis work, a methodology for managing information linked to CAO models in order to integrate expert information that we call semantic into these CAO models. The frozen CAO models handled are usually in low-level formats such as STL, IGES or STEP AP203. They are used as input data for our methodology and they can be associated with product definition data, such as a product drawing or documents. The processing of CAO models requires a solution that is able to_manage the digital models and the information they couId possibly integrate. And also the incompleteness of some CAO models that is linked to the 3D format or to the limit of the technology used to obtain the CAO model (e.g. software li mit, 3D format for geometric representation only and that does not support a representation of the construction tree or that cannot graphically represent geometric dimensions and tolerances, etc.). Finally, the relevance of integrated information into CAO model, of a non-geometric nature, during the semantic overlay phase should make it possible, in certain cases, to produce parameterised CAO models, specific to the activity of the application domain. The state of the art, concerning the information representation contained in CAO model and the management of this information, makes it possible to identify techniques and approaches that help the semantic enrichment of CAO models at various levels of granularity. This thesis proposes a methodology named Vaquero For CAO Semantic Enrichment (VFCSE), which is made of three step access, identification and annotation. The aim of this methodology is to integrate missing and standardised information of a non-geometric nature, such as product specifications, tolerances, geometric dimensions, etc., into frozen CAO models. This information will be derived from user needs working on the CAO model and will corne from a semantically rich standard in order to be useful for many operations related to the product life cycle. The enrichment, thanks to this semantically rich standard, will allow for a perpetuation of the information and an efficient reuse of CAO model information. ln order to do this, a CAO model is retrieved from a PDM (Product Data Management) thanks to a user request. lt is visualised in a CAO viewer supporting STL, IGES and STEP AP203 formats. Then, follows a step of identifying components of CAO model. These components can be parts or assemblies. The identified components are annotated based on the STEP AP242 format, which represents the semantically rich standard. These annotations are stored in a standardised ontology, which serves as a minimal basis for carrying all the semantics to be integrated into the CAO mode in order to make the CAO model durable and reusable. The scientific contribution of this work is mainly based on the possibility of reverse engineering by using ontologies to annotate 3D models, according to user needs who has the CAO model at his disposal

Recently, due to the rapid world population growth, decreasing of natural resources and raw materials, increasing environmental awareness, interesting for wasting raw materials, using produced products more efficiently, and reusing of sources is rapidly increasing. Nowadays, reverse logistics as an important business strategy for profitable and sustainability is becoming important. The effective implementation of reverse logistics gives companies a competitive advantage in sectors. Due to mentioned reasons firms intend to incorporate reverse logistics activities such as the recovery, remanufacturing, recycling or disposal. Reverse logistics has become increasingly important as a profitable and sustainable business strategy. Therefore, more and more manufacturers have adapted the practice of recovering value from returned products and integrate product recovery activities into their processes. The electronic industry is one of the fastest growing manufacturing industries and the main purpose of this chapter is to explore the opportunities for waste returns within this sector.

Full textAbstract:
Advancements in capabilities for machine learning and artificial intelligence (MLAI) has led to growing questions and challenges for effective sociotechnical MLAI applications. It is important to consider applications outside of consumer product development, particularly in the realms of local, regional, national, and international policy development. There are intriguing opportunities to apply MLAI techniques to improving the efficiency of standard government (“bureaucratic”) activities, including policy and diplomatic operations. Growing sociotechnical concerns address the limitations of applying machine learning tools to digital content, due in part to the unintentional (or even explicit) embedding of bias and prejudice into MLAI algorithms that become more difficult for others (particularly those without computer science training) to detect, correct, or reverse. The author’s experience provides context to consider issues of MLAI involvement in policy creation in a more subtle operational context. Many MLAI applications are built on the analysis of an existing corpus of outcome products; this reasoning might be applied to the analysis of international policy and standards documents. This paper addresses two challenges to that approach. One is the difference between engineers and policymakers on the nature of debate, evidence, and conflict resolution. A second difference addresses, from the author’s experience, emphasis on informal and interim processes, rather than final products, in the development of mutually agreed outcomes in national and international policymaking efforts.

THE PETROPHYSICS PLAY A KEY ROLE IN THE REDEVELOPMENT STRATEGIES, ACTING INTEGRATED WITH GEOLOGY, RESERVOIR ENGINEERING AND OPERATIONS. A GOOD STATIC MODEL IS ONE OF THE MOST IMPORTANT PREMISES WHEN STUDYING A RESERVOIR, APPLYING HIGH-RESOLUTION STRATIGRAPHY TECHNIQUES, IDENTIFYING RESERVOIR CONNECTIVITY AND FLOW UNITS. IN ADDITION, THE INTEGRATION BETWEEN PETROPHYSICS AND RESERVOIR ENGINEERING HAS A CRUCIAL ROLE IN THE ESTABLISHMENT RESERVOIR DEPLETION LEVELS AND ESTIMATING CURRENT WATER SATURATION AND OIL-WATER CONTACT DISPLACEMENT. THE USE OF CASED HOLE TOOLS SUCH AS PULSED NEUTRON LOGS AID IN THE RESERVOIR MONITORING, IN THE IDENTIFICATION OF BYPASSED OIL ZONES AND SIGNIFICANTLY REDUCES RISKS IN WORKOVER ACTIVITIES. IN THIS PRESENTATION IT WILL BE DESCRIBED WORKFLOWS AND TECHNIQUES OF HOW PETROPHYSICS WAS APPLIED IN THE CONCEPT OF MATURE OILFIELD REDEVELOPMENT, WHICH LED TO AN INCREASE OF RESERVOIR PRODUCTIVITY IN OVER 60%.

Student engagement in traditional teacher centered model of teaching is limited to independent working or working in a small group on a task designed by the teacher. Flipped classroom is a blended learning strategy that reverses the traditional educational arrangement by delivering instructional content, often online, outside of the classroom and moves activities, including those that may have traditionally been considered homework, into the classroom. Various studies support and recommend flipped model of teaching at graduate and undergraduate level but very less have analyzed the impact of flipped classroom on academic performance and especially knowledge creation at post graduate level. In this paper we are analyzing the performance and knowledge creation of master's level students using Data Mining Techniques in a flipped classroom model.

Full textAbstract:
Reverse engineering is a common design strategy in industry. It is a term that has come to encompass a large array of engineering and design activities in the literature; however, in its basic form, reverse engineering is simply the process of extracting information about a product from the product itself. Depending on its use, it may or may not be advantageous to utilize a reverse engineering strategy. As with any rational decision, reverse engineering is only favorable when the benefits from its use outweigh the investment. Therefore, a general understanding of the principles that increase the difficulty or investment required to reverse engineer mechanical products would be helpful for everyone affected by reverse engineering activities. In this paper, we articulate and explore these fundamental principles by reviewing several examples from the literature and from our own experience. We then use the principles as a basis for the development of a methodology to build barriers to reverse engineering into new products, and provide a simple example to illustrate its use.

In Reverse Engineering, commercial solutions such as Geomagic™ or RapidForm™ or CAD software such as CATIA™ provide very efficient toolboxes that enable to rebuild geometry. Moreover, some of them provide segmentation algorithms, sketchers and/or many other facilities rebuilding tools in order to help to recover the original surface. Those software’s enable to rebuild the geometry of a technical object as a set of functions (protrusion, revolution, sweep…), they enable to add colours and textures, and they enable realistic kinematical animation and many other things. Unfortunately, all those toolboxes present a lack of geometry analysis tools. The geometry of a given product is the consequence of a complete process, it is important, considering Reverse Engineering activities, to try to recover any evidence of its past life (including socio-economical aspects, the design intents of the former designer, its different uses…) from its geometry in order to produce a good quality 3D model. Such models can provide important possibilities for Reverse Engineering. It enables to study the product more efficiently than a geometrical model based on a mesh or on free form surfaces. This paper proposes approaches and methodologies for using knowledge to rebuild CAD model to the best closer to the original CAD model that could have been obtained by the original designer. Such a model is feature based. They can be functional features or manufacturing features. For a good rebuilt of 3D model, the geometry of these features is driven by parameters, rules and relationships that are provided by the former designer.

Full textAbstract:
Reverse engineering is the process of extracting information about a product from the product itself. An estimate of the barrier and time to extract information from any product is useful for the original designer and those reverse engineering, as both are affected by reverse engineering activities. The authors have previously presented a set of metrics and parameters to estimate the barrier and time for product reverse engineering. This work has laid the foundation for the developments of the current paper, which address the issue of tolerance extraction during reverse engineering. Under the developments presented herein, measurement and statistical analysis of the variation between multiple samples of a product are required to reverse engineer its tolerances. When reconstruction is the reason reverse engineering activities are carried out, this level of reverse engineering can be critical, as tolerances ensure that products function properly and consistently. In this paper, we introduce metrics that (i) characterize how the flow of information from a product during reverse engineering changes as additional product samples are evaluated, and (ii) estimate the total barrier and time to reverse engineer the tolerances of a product. Additionally, a simple example is introduced to illustrate how to use the newly developed metrics and to serve as empirical validation.

Full textAbstract:
The Purdue College of Technology in Columbus recently offered for the first time a class in Dimensional Metrology. Similar classes have been offered in the past but this was the first that focused on dimensional metrology. In keeping with its hands-on, project-based learning philosophy, the class mixes many laboratory activities with the lecture component of the class. The laboratory activities focus on accomplishing some engineering function that requires measurement. These activities are not just a matter of measuring a few items with the tools. There is always a clear engineering or manufacturing objective with each laboratory activity. In some cases, this may also include a reverse-engineering project that incorporates a measure-manufacture-measure iterative cycle to determine the effectiveness of the manufacturing operation. This work will discuss in detail those experiments utilized in the class. Some examples include gage R&R studies, a calibration exercise, determining constants of springs, measuring threads and measuring gears. Ultimately, the addition of realistic and engaging measurement activities to a class serves to better prepare students for careers in product design and manufacturing.

Full textAbstract:
Industrial companies are confronted to reverse engineering on mechanical components. They have to define a new process planning from 3D information (points cloud, drawings, etc.). The component has to be re-engineered in order to improve and optimize new manufacturing processes. According to surveys, reverse engineering approaches begin to be supported by Knowledge Base engineering Systems (KBS). These systems are efficient to quickly obtain CAD models based on functional features. These models are successful for redesigning activities and then for defining a process planning. Industrial companies often need to re-engineered components in order to define directly a new process planning. In this case CAD models, based on functional features, are not useful. This paper suggests an approach called Reverse Engineering For Manufacturing (REFM) which allows to directly obtain a CAPP (Computer Aided Process Planning) model from 3D information. The system management is based on Design For Manufacturing (DFM) approach and enables to manage manufacturing information (such as the number of fixtures, the kind of milling operations, etc.). In addition, this system management allows to define process planning alternatives. The aim of the paper is to show the concept of REFM approach according to a use case.

Disassemble/Analyze/Assemble (DAA) activities involve the disassembly, analysis, and assembly of an artifact. Such activities are frequently made a part of the undergraduate engineering curricula in the United States (and elsewhere) as they provide useful ‘hands-on’ active learning components that can be easily integrated into various courses. DAA activities are central to product dissection and reverse engineering, terms which have been used interchangeably in the engineering design education literature and course titles. In some cases these activities are coupled with redesign activities, paving the way for a good context and providing a background for a meaningful engineering design. Despite this fact, however, based on our review of the literature it is not clear how do these DAA activities help with the redesign activity, if at all. Accordingly, in this paper we present results of our data collection that aimed at uncovering students’ perception regarding if DAA activities help with redesign (e.g., is it easier to redesign after dissection?). Overall, students had positive perceptions toward dissection, specifically with regards to its impact on redesign. We also report on the relation of student perceptions to design task, team functioning, and tolerance for ambiguity.

Full textAbstract:
Reverse Engineering methods are becoming more and more important in product development processes in cases without CAD models or modified physical objects. For numerical calculations of scanned components, using, for instance, the Finite Element Method (FEM) to look at strength or vibration characteristics, we need the previously scanned data, obtained via Geometric Reverse Engineering, to be converted into CAD surface data, a Finite Element-meshing and a determination of material parameters and constraints. Tremendous effort must be expended in the course of performing repeated Geometric Reverse Engineering and FE-meshing, which must be done when there are iterative, largely local changes in real geometry (such as when incorporating forming dies) or in the case of topologically similar objects, which must be scanned again and again. This project is aimed at the generation of new calculation models using an appropriate adaption of existing FE meshes (made using a CAD model, for example) or FE meshes previously created with the help of scan data through the retention of intelligent meshing (constraints, material, element type etc.). In terms of their topology, these new meshes should adapt themselves to changes in geometry. Time-consuming Geometric Reverse Engineering, as well as re-meshing, can thus be bypassed. Product development cycles frequently proceed in an iterative manner. Repetition of process steps is intended to improve the product in order to achieve an optimum result in design and dimensioning. The goal of these research activities is to reduce the process steps from 3D scan data to FE-meshing, in particular in development cycles. The paper introduces the project’s concept, its initial results, and further steps.
