摘要

This article aims to compare three different approaches already proposed by the authors regarding the three-dimensional error stack-up analysis in machining. Although the developed error stack-up analysis method comprises of different manufacturing processes, this article is limited to machining operations. This article is built on the previous research of the authors namely the model of manufactured part (MMP) which models the different geometrical deviation 3D impacts on the geometrical and dimensional quality of part produced (error stack-up) in a multi-stage (MS) machining process. In this study, the MMP will be used for developing numerical solution techniques for the aim of tolerance analysis in a MS machining process. The developed solution techniques are classified in two main categories: worst case analysis (WCA) (worst part produced) and stochastic analysis (STA). This article provides an overview of the MMP model and the different solution techniques. The different strategies to simulate the deviation parameters of the model are then discussed. For each of the three proposed solution techniques, its advantages and disadvantages are explored in detail. The performance of the solution techniques is then compared from different points of view (i.e. rapidity, convergence to the global minimum and analysed case … ) through a 3D example, and finally some perspectives are presented.View full textDownload full textKeywordstolerance analysis, process plan evaluation, errors stack-up, model of manufactured partRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/0951192X.2011.627943
