Abstract:
In order to manage the version files and maintain the latest version of the computer-aided design (CAD) files in asynchronous collaborative systems, one method of version merging for CAD files is proposed to resolve the problem based on feature extraction. First of all, the feature information is extracted based on the feature attribute of CAD files and stored in a XML feature file. Then, analyse the feature file, and the feature difference set is obtained by the given algorithm. Finally, the merging result of the difference set and the master files with application programming interface (API)

In this paper, the 3D model of the centrifugal fan impeller will be obtained using CAD software (CATIA). The blade will be obtained with 4 design methods: constant blade width and variable blade angle; hyperbolic blade width and variable blade angle; hyperbolic blade width and constant blade angle; linear blade width and variable blade angle. A comparative analysis of the weight of the blade, as well as of the weight of the rotor composed by cascade of blades, front and rear shrouds will be presented. Two materials have been used for all the elements of the centrifugal fan impeller: steel and

Abstract This article provides the fatigue life estimation of the frame of a new electrically powered shuttle used in airports and resorts. The frame and components of the electrically powered shuttle were designed by expert employers of the OSCAR Co. using a CATIA computer program. Accelerometers were mounted under and above the prototype electric vehicle frame and external load path interaction data were collected by road tests. By means of five varied degrees of road roughness and three different conditions for vehicle loading, the raw road data were recorded via accelerometers on the vehic

Abstract:
This paper focuses on the development of a multi-axis post-processor engine with a curvature-based feed adaptation module, capable of extracting generic CNC data for high precision machining. The motivation of this work stems from the drawback of standard and commercial post-processors to modify their internal source codes so as to be implemented to newly-developed functions which integrate modern CNC units. The multi-axis post-processor proposed in this work operates as a stand-alone function of an artificial intelligent module that optimizes machining parameters for standard swept cut multi-

Abstract:
This paper presents three methods of converting complex 3D models of STL type into solid models. For converting the STL models, specific approximation functions from CATIA and Creo Parametric software were used as well as 3D solid modeling methods that used sketches drawn for sections of the specific analyzed model. This conversion is required to get a solid 3D model that can be used for finite element analysis and to be processed using Boolean functions in specific CAD programs.

Abstract:
In this paper, we propose a method for text-query-based keyword spotting from online Chinese handwritten documents using character classification model. The similarity between the query word and handwriting is obtained by combining the character classification scores. The classifier is trained by one-versus-all strategy so that it gives high similarity to the target class and low scores to the others. Using character classification-based word similarity also helps overcome the out-of-vocabulary (OOV) problem. We use a character-synchronous dynamic search algorithm to efficiently spot the query

Abstract:
The detailed China Fusion Engineering Test Reactor (CFETR) 22.5° computer aided design (CAD) model is very difficult to convert into Monte Carlo N Particle Transport Code (MCNP). Manually writing MCNP input data is complicated, which is not only time-consuming but also cannot guarantee accuracy. Therefore, in order to improve the efficiency and accuracy of model transformation, modeling with CAD using CATIA is introduced, and MCNP files are converted by ANSYS. This is because ANSYS has a function that converts CAD “stp” format to MCNP input in the geometry section. Meanwhile, ANSYS can also re

Today, image forgery is common due to the massification of low-cost/high-resolution digital cameras, along with the accessibility of computer programs for image processing. All media is affected by this issue, which makes the public doubt the news. Though image modification is a typical process in entertainment, when images are taken as evidence in a legal process, modification cannot be considered trivial. Digital forensics has the challenge of ensuring the accuracy and integrity of digital images to overcome this issue. This investigation introduces an algorithm to detect the main types of p

Le grenaillage ultrason est un procédé mécanique de traitement de surfaces. Il consiste à projeter des billes à la surface de pièces métalliques, à l’aide d’un système acoustique vibrant ultrasonore. Lors du traitement, les billes sont contenues dans une enceinte spécialement conçue pour la pièce à traiter, et adoptent un comportement similaire à celui d’un gaz granulaire vibré. Le grenaillage ultrason sert à introduire des contraintes résiduelles de compression dans le matériau traité. Ces contraintes de compression sont bénéfiques pour la tenue en fatigue de la pièce et sa résistance à la co

Although modern machine tools and controllers have evolved along with the personal computer over the years, the standard input (M&G code files) for CNC machines has not changed. A new method of control called Direct Machining And Control (DMAC) is being developed at Brigham Young University. DMAC is a revolutionary new paradigm for rapid prototyping and CNC control by directly connecting a CAD system with software based DMAC controller. DMAC technology completely eliminates all intermediate files (APT, M&G code, STEP-NC, etc) between the CAD model and the CNC controller by directly pro
