In this sense the error modeling approach becomes imperative. In this paper, a new statistical model which based on forward kinematics is presented. Firstly, the structure of joint clearance and 6-dof parallel manipulator is analyzed and simplified. The forward kinematics process is applied to identify the pose of the manipulator for sample set of link lengths and corresponding pose error can be obtained subsequently, then the statistical method is used to investigate the characters of pose errors. Finally the contributions of the research are highlightened by means of comparative simulations.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123301105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In GM all systems have a virtual counterpart that actsautonomously, this includes both complete manufacturing systems and the products. The control system required for this approach is based upon a distributed and hybrid architecture, using agent technology. An important aspect in the paradigm is the product manufacturing description. This paper introduces the concept of an architecture where the control of the manufacturing is abstracted from the product manufacturing blueprint. A product is delineated step by step by specific services in the grid. The proposed system increases flexibility twofold, first by enabling abstraction of product's parts and second by dynamically using manufacturing means.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125277725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been considerable progress in micro-manufacturing capabilities by μEDM in recent years. Nevertheless there still exist a few challenges in terms of process accuracy and efficiency, and the achievable shape accuracy in micro-EDM milling is limited to 3-4 microns in vertical direction and 2-3 microns in plane. In order to reach zero-defect manufacturing with this micro-sparking technique, a holistic approach for precision micro-EDM milling is pursued at Leuven University. To improve the overall performance of the micro-EDM milling process, various upgrading has been carried out on a SARIX® machine, which includes monitoring and controlling of the stability of the sparking process (gap variation and energy distribution etc.), wear compensation of the tool-electrode, and on-machine metrology. Preliminary experiments have been carried out with promising results, and further system integration and application on industrial demonstrators are in progress.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132364308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is applied to regularized Boolean operations including union, difference, and intersection. This approach is better than other methods because three optimizations have been introduced. First, the constructed topology information improves the data structure from discrete triangles to point indices, face indices, and their connectivity information. Second, the space dividing algorithm has improved the computational complexity from O (m * n) to O (k (log K)). Third, the tessellation has enumerated a number of special triangle-triangle intersection examples, which are then dealt with separately. Finally, this method is implemented by a program written in C++ and OSG. With some examples, this system is proved to be efficient and robust.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132464901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, rigid and constant preloads are used to apply uniform forces on the bearing. However, considering the machining errors, assembly errors and load conditions, the uniform preload actually manifests as a non-uniform load distribution in ball bearing. The work presents a method to analyze the bearing characters under the different preload conditions. Under non-uniform preload the bearing outer ring is rotated at a small angle with respect to inner ring. In this occasion, the stresses and deformations of rolling elements at different azimuth angles diverse from each other. As a result, the bearing stiffness is also different from that under uniform preload. In this paper, the bearing deformation and stiffness under different uniform and non-uniform preloads are analyzed using nonlinear finite element method. The results show that the relationship between axial stiffness and axial preload are nonlinear. The bearing angular stiffness increases nonlinearly with the equivalent moment under non-uniform preload.","PeriodicalId":323666,"journal":{"name":"2013 IEEE International Symposium on Assembly and Manufacturing (ISAM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131404204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is essential to guarantee the spindle rotary accuracy for improving the machining quality. Spindle rotary accuracy is determined by bearing accuracy and other components' geometric error. Firstly, a 5-DOF bearing model is applied to describe the position and orientation deviations between inner ring and outer ring. It is also used to describe bearings' rotational error. Secondly, the distance of curvature centers of inside and outside raceways is calculated when the position and orientation of inner ring changes, in consideration of the dimensioned and form errors of the inner, outer rings and balls. Small Displacements Torsor (SDT) is used to describe machining error of spindle.
