Abstract:

Conventional design of jigs and fixtures has become unsuitable given the requirements of modern technology and complexity and diversity in the production with the rapid update of products. Computer-aided design (CAD) of jigs and fixtures is an effective solution in this direction. The current paper focuses on a computer-aided design of the traditional jigs and fixtures and developed a system containing tailor-made software, created using the Visual Basic programming language and installed on it the viewer screen to show the part. The developed system has been built by connecting Visual Basic programming language to the SolidWorks software on which the part is drawn and saved as STEP AP-203 file format, and the system reads and extracts the data from the STEP AP-203 file. Heuristic rules of feature recognition are pre-prepared for checking the extracted geometric data and deciding which data shape will represent the machining feature; then, the system provides the optimum design of the traditional jigs and fixtures for a group of hollow cylindrical parts that contain a group of cross-holes on the cylinder body, whether perpendicular or offset from the cylinder’s axis, (inclined or inclined offset, or blind or through, by applying pre-prepared heuristic rules for the design of traditional jigs and fixtures.

Abstract:

This paper provides a design technique of support for being applied in fast fabrication on plastic prototype, the plastic part developed through the computer aided design (CAD) can be rapidly fabricated by a CNC machining center without needs of any specific jigs or fixtures, the function provided is similar to a rapid prototyping (RP) machine used for fabricating the sampling part. By the testing result, the provided design technique of support can not only be applied in the part required for a dual-surface (or multiple-surface) processing, but also applicable for fabricating the part having thin housing. As such, this paper provides another economical and efficient option besides the RP.

Abstract:

Composite structures in aeroplanes are often thin-walled and lightweight, resulting in significant compliance, which presents a handling and assembly challenge due to the associated part deformations. In order to counteract these deformations, the parts are held in their specified geometry using stiff and correspondingly heavy fixtures or jigs. Mobile industrial robots are very versatile and widely used in industrial volume production, but they are limited in their payload capacity. High-rate production of large aerospace modules requires highly automated flexible assembly processes. The approach presented in this paper is to combine mobile units with lightweight assembly jigs that have the capability of deformation compensation. The subject of the study is a high-rate assembly process for flap modules using an Autonomous Industrial Mobile Manipulator (AIMM) and a lightweight end effector. The end effector has a shape compensation function, implemented by an integrated Stewart platform, which enables the compensation of manufacturing tolerances as well as gravity effects. The compensation function is used in a closed loop and counteracts shape deviations by appropriate fixture shape adjustments. The paper reports on the conceptual design of the assembly scenario, the design of the end effector, its realization and the successful experimental demonstration at 1:1 scale.

Abstract:

The long lead time for jig and fixture design is a serious bottleneck in modern manufacturing. Efforts to automate the design process using intelligent CAD systems have not been taken beyond the prototype stage mainly because of several impediments. These include the requirement of complex data structures to represent the workpiece and its attributes. Two deficiencies in existing systems for fixture design are addressed. These are (a) design for a sequence of operations and (b) design with tolerance considerations. Tolerance and process specifications are obtained from the user during an interactive session. A knowledge-based design system, REFIX, then designs a fixture for the workpiece. The fixture is optimized for a particular datum specification and sequence of operations. It is then analyzed and presented via the CAD system. REFIX is automated to minimize user-induced errors.

Abstract:

Proses produksi telah banyak berevolusi dengan diperkenalkannya konsep manufaktur inovatif yang handal. Salah satu komponen mesin yang banyak diproduksi adalah cylinder head. Cylinder head harus tahan terhadap temperatur dan tekanan yang tinggi selama engine bekerja. Oleh sebab itu umumnya cylinder head dibuat dari besi tuang. Kendala yang ada saat ini yaitu proses pembuatan cylinder head kurang efektif dan efisien karena ketika menetapkan sudut untuk membuat reamer berbasis manual, selain itu setting benda kerja tidak otomatis sehingga membutuhkan waktu yang terlalu lama. Solusi dari permasalahan tersebut yaitu dengan adanya jig dan fixture. Metode penelitian yang digunakan adalah metodologi perancangan fixture (Society of Manufacturing Engineers). Berdasarkan hasil analisis, terdapat kelebihan dari jig dan fixture yang telah dirancang ulang yaitu: 1) memiliki stoper yang berfungsi untuk memberhentikan benda kerja, dengan sudut yang sudah ditentukan sehingga tidak perlu mensetting sudut kembali; 2) tidak mudah bergeser apabila fixture dipasang dan sejajar di meja frais; 3) terdapat dua engsel sehingga lebih balance; 4) pemasangan tidak rumit sehingga tidak memakan banyak waktu dalam pembuatan produk.Kata kunci: Jig and fixture; redesign; head cylinder The production process has evolved a lot with the introduction of innovative reliable manufacturing concepts. One of the engine components that are widely produced is the cylinder head. The cylinder head must withstand high temperatures and pressures while the engine is running. Therefore, generally the cylinder head is made of cast iron. The current constraint is that the cylinder head manufacturing process is less effective and efficient because when setting the angle to make the reamer a manual basis, besides that the workpiece setting is not automatic so it takes too long. The solution to this problem is the presence of jigs and fixtures. The research method used is the fixture design methodology (Society of Manufacturing Engineers). Based on the results of the analysis, there are advantages to the redesigned jig and fixture, namely: 1) it has a stoper which functions to stop the workpiece, at a predetermined angle so that there is no need to set the angle again; 2) it does not move easily when the fixture is installed and parallel to the milling table; 3) there are two hinges so that it is more balanced; 4) installation is not complicated so it does not take much time to manufacture the product.Keywords : Jig and fixture; redesign; head cylinder.

Abstract:

Computer-aided fixture design (CAFD) techniques have advanced to the point that fixture configurations can be generated automatically, for both modular fixtures and dedicated fixtures. Computer-aided fixture design verification (CAFDV) is a technique for verifying and improving existing fixture designs. This paper introduces a first comprehensive CAFDV framework which uses both geometric and kinetic models to verify locating completeness, locating accuracy, and fixturing stability. The models can be also used for locating tolerance assignment and the determination of minimum clamping force required in machining operations. The system is integrated with commercial CAD package and applied in industrial real-cases.

Abstract:

Productivity is one of the most important factors in manufacturing processes because of the high level of market competition. In this regard, modular fixtures (MFs) play an important role in practically improving productivity in flexible manufacturing systems (FMSs) due to this technology using highly productive computer numerical control (CNC) machines. MFs consist of devices called jigs and fixtures for accurately holding the workpiece during different machining operations. The design process is complex, and traditional methods of MF design were not sufficiently productive. Computer-aided design (CAD) software has rapidly improved as a result of the development of computer technology, and has provided huge opportunities for modular fixture designers to use its 3D modelling capabilities to develop more automated systems. Computer-aided fixture design (CAFD) systems have become automated by the use of artificial intelligence (AI) technology. This study will investigate the further improvement of automated CAFD systems by using AI tools. In this research, an integrated CAFD is developed by considering four main requirements: · a 3D model of the workpiece, · an expert system, · assembly automation of MFs, · an efficient feature library. The 3D model is an important factor that can provide the appropriate specification of the workpiece; SolidWorks is used the CAD environment for undertaking the 3D modelling in this study. The expert system is applied as a tool to make right decisions about the CAFD planning process, including locating and clamping methods and their related element selection. This helps achieve a feasible fixture design layout. SolidWorks API and Visual Basic programming language are employed for the automating and simulation of the assembly process of MFs. A feature library of modular fixture elements is constructed as a means to simplify the fixture design process.

Abstract:

The magnetization of the permanent magnet components is a key enabling technology in the production of permanent magnet based electromagnetic devices. Although recent advances in the properties of rare-earth magnets, offer considerable scope for enhanced device performance, in order to realise such improvements, the permanent magnet must be magnetized to saturation. This is a considerably more onerous requirement for the rare-earth materials as compared to the more established permanent magnet materials, particularly if the preferred production route of single step, multipole magnetization of either the part or fully assembled device is to be employed. To enable accurate design of magnetizing systems for such demanding applications, an integrated computer-aided design methodology has been developed. It is based on both analytical and finite element field calculation techniques, and spans the entire design synthesis from initial specification through to the assessment of the performance of the final device into which the magnetized magnet is incorporated. Particular attention is directed towards the role of eddy-currents during the impulse magnetization, and to this end a transient, electric circuit coupled finite element simulation is described. A case study is presented on the relative merits of magnetizing the anisotropic NdFeB magnet of a brushless D.0 motor at various stages during the motor production. A further case study on the magnetization of an isotropic bonded NdFeB multipole rotor highlights the additional considerations that arise in the design of magnetizing fixtures for isotropic materials. Finally, the utility of the methodology in designing a limited range of axial multipole fixtures is demonstrated with a case study on a fine pole-pitch axially magnetized ring magnet.

Abstract:

Tooling design for manufacturing processes refers to direct tooling for making a part such as molds and dies for injection molded parts and metal stampings, or for supporting machining operations such as jigs and fixtures. This paper summarizes some of the R&D activities in those areas over a period of 20 years in the Department of Mechanical Engineering, National University of Singapore. It is notable that increasing use of computer tools has turned what is used to be known as a “black art” into a discipline embracing both heuristic and scientific analyses.

Abstract:

Abstract Jigs and fixtures are indispensable tools in various manufacturing processes. These processes include metal removal, assembly, welding, and inspection processes. Not only do jigs and fixtures facilitate the operations, but also provide quick loading/unloading, proper and consistent supporting and locating of a workpiece. As a result, the workpiece can be manufactured economically in proportion to the volume of production. With the advent of computer aided design and computer aided manufacturing together with an increasing power of both computer hardware and software, computerized fixture design systems become feasible and more sophisticated. The current computerized fixture design systems are developed utilizing several approaches ranging from simple interactive placement of fixture components to sophisticated generative systems. However, one of the common drawbacks of these systems is a lack of process planning integration in the fixture design considerations. As a result, the contradiction between fixture design generated by the computerized fixture design system and a process plan generated by a process planner or by computer aided process planning software always occurs. In other words, the fixture set-ups and workpiece orientation are not congruent to the process plan. This paper serves to discuss a solution to the problem mentioned above. A mathematical model was developed to integrate process planning in fixture design considerations. An optimized fixture design system will be presented and discussed. Examples of tested cases are also presented.

Abstract:

The purpose of this study is to develop the integrated design system of supports, which are turning roller, dent pad and bracing pipe to control distortion of the pressure vessel. The optimum design condition for each support was established by analytical solution and finite element analysis with simple model and verified by comparing with the results of FEA for actual model. Based on the results, the Window-based computer program was developed using Visual C++. The program supports component feature-based modeling. In addition, user can easily determine the condition of supports and jigs during manufacturing of pressure vessels with user-friendly functions such as the material database of ASME, easy input, and detail output.

Abstract:

Computer-aided fixture design (CAFD) techniques have been advanced rapidly that fixture configurations can be generated automatically, for both modular fixtures and dedicated fixtures. Computer-aided fixture design verification (CAFDV) is the technique for verifying and improving existing fixture designs. In this paper, the framework of CAFDV is introduced with two based on two models, geometric and kinematic models. The fixturing tolerance and stability verification will be presented in separated papers.

Abstract:

Most of previous computer aided fixture design (CAFD) research has mainly concentrated on machining fixtures rather than welding fixtures, and how to face the challenges such as dynamic requirements, expansion, maintenance and management in the development of complicated computer aided welding fixture design (CAWFD) software system has received much less attention. Application of Unified Modeling Language (UML) and Object-oriented Design Pattern (OODP) for developing CAWFD software system has been discussed in this paper. CAWFD system functions like design phases, workflow and design subtasks in each design phase are introduced. How to employ UML fundamental elements such as use case diagram, class diagram and component diagram to model the CAWFD system has been demonstrated. Multiple-tier architecture of CAWFD and its benefits are also presented. OODP has been certified to be an effective and efficient method especially for class diagram creation and refinement which is the key point during system analysis and design. Due to the complexity of CAWFD, the class diagram for CAWFD is classified as conceptual class diagram and detailed class diagram. How to use Model-View-Control (M-V-C) design pattern in conceptual class diagram and the benefits of M-V-C application are discussed. For detailed class diagram, the techniques of applying Command, Observer, Factory and Template patterns to realize code reuse are articulated. As a result, the extension, reusability and maintainability of CAWFD system can be obtained by applying UML and OODP.

Abstract:

This paper presents the development as well as the architecture of a computer-aided dedicated fixture design system intended to support the design of lightweight (carbon fiber composite) grippers for a major truck company. Lightweight grippers were required due to the increasing production rates in the automotive industry. The current robotic equipment was facing diverse problems during transportation and aligning of the parts, problems related to mass inertia, accuracy and stability. Moreover, the increased demands for truck customization and fast release of new product versions required a computer-based support for the design of the appropriate fixtures. This application is believed to be of interest for fixture research because the design of such complex fixtures is likely to appear more and more often. Specifically, such fixtures are subject to specific requirements that necessitate a systematic requirement elicitation method; they also require extensive conceptual design work as well as careful analysis activity planning. The main steps requisite for the development of the design system are reported: setup planning, fixture planning, conceptual design of the gripper. The architecture, the process and the constituent elements of the design system are also described and illustrated.

Abstract:

Abstract Flexible fixturing is a necessary aspect of flexible manufacturing systems (FMS) and computer-integrated manufacturing systems (CIMS). Modular fixtures are most widely used in industry for job and small batch production. Computer-aided fixture design (CAFD) has become a research focus in implementing FMS and CIMS. Fixture configuration design is an important issue in CAFD. A review of the current research in CAFD indicates that one major problem impeding the automated generation of fixture configuration design is the negligence of study on fixture structures. This paper investigates fundamental structures of dowel-pin modular fixtures and fixturing characteristics of commonly-used modular fixture elements. A modular fixture element assembly relationship graph (MFEARG) is designed to represent combination relationships between fixture elements. Based on MFEARG, algorithms are developed to search all suitable fixturing unit candidates and mount them into appropriate positions on baseplate with an interference checking. A prototype system for automated design of dowel-pin modular fixture configurations is presented in this paper. Fixture design examples are given in the end of the paper.

Abstract:

Fixtures are important components in manufacturing systems. Fixturing changes because of manufacturing changing from mass production to production in smaller batches and higher variety of products. Computer-aided fixture design (CAFD) systems automate the process of fixture design and verification. Research work has mainly concentrated either on automating the CAFD process or on making it user-friendly and interactive. However a final fixturing scheme may not be optimal because different users may need fixtures to meet different requirements, this paper proposes a conceptual module for the fixture validation to compare, test and analyze various combinations of fixturing elements. A fixture validation model is developed using a virtual reality (VR) system to support the idea presented in this paper.

Abstract:

A crucial factor in the success of developing integrated manufacturing systems lies in the ability to exchange information among the various computer-aided systems. Although a vast amount of research has been conducted on computer-aided fixture design systems, the need for information exchange between a fixture design system and other manufacturing systems has not been dealt with thoroughly. Models for the exchange of information within an enterprise or within an extended enterprise depend on the functionality and behaviour of individual enterprises. One means of developing an information model for an enterprise is to determine the information requirements by modelling the enterprise. However, this results in a monolithic model that is only applicable to that enterprise. As a solution to this drawback, we describe the development of a reference model for fixture design information support, which can be instantiated to be applied to different types of enterprises. We concentrate on machining fixtures and information form the fixture design domain to other domains.
