Digital Assembly Process Planning Based On Tecnomatix And Post-processing

With the continuous development of science and technology, each componentpart of the percentage in the entire product life cycle has changed significantly.Product assembly as a key step for product quality has also gradually increased inthe product life cycle, and more attention has been paid on it. Although thepopularity of computer-aided design system CAPP have a profound impact on theassembly operations, but there are still2D drawings contain limited information andcan not exactly representate the complex assembly constraints of the products,process card and text description are ambiguous and not easy to storage and access,it also can not get rid of the shortcomings of the trial of physical prototypes and tryassembly verification problems, digital assembly provides a new way of thinking tosolve the above problems. This article is to study the products of the digitalassembly under the Tecnomatix platform, and process the data.Firstly, for assembly modeling techniques, a model for assembly sequenceplanning pretreatment modeling method has been put forward, this method gives thetwo different modes of pretreatment, and compare the two methods in advantagesand disadvantages; Furthermore, man-machine interactive simulating disassemblysequence planning method based on the idea of removable can be installed along thereverse of the disassembly sequence has been proposed, planning assemblysequence by controlling hidden property of parts to simulate disassemble after theassembly structure is divided, and it studied how to achieve it under the Tecnomatixpaltform; What’s more, it also put forward interference removing path planningmethod based on the idea of “detachable can be installed”, and gives the pathplanning of two methods, it also has studied how to realization methods under theTecnomatix platform.Secondly, it studies the generation of process document, using database andprogramming technology to achieve the separation of process information anddocument format, network editing of document, proofreading, browsing and inquiryand so on.Finally, using the assembly of two-leveled gear retarder as an example toconduct instance validation under the Tecnomatix platform and processpost-processing platform.
