The Digitalization Design Of Key Spare Part Of Cigarette Machine And Its Manufacturing Basic With Reverse Engineering

The key spare part of cigarette machine is the important part of the cigarette machine, with the improvement of the automatic degree,the structure of the key spare part is becoming more complicated, the complicated curved surface increases, more and more key spare part of cigarette machine need to be producted by oneself.The research of reverse engineering is the important means improving quality of the key spare part of cigarette machine.According to department reality ,this subject mainly rounds the typical spare part of cigarettemachine ,studies the relevant principle and method of the whole course from the digitalization design of the spare part to its digitalization manufacturing.It analies the organization characteristics of cigarette machine ,the importances of the key spare part in cigarette production and the problem which the spare part exist while making key spare part by oneselves. This subject puts forward the main matter of being studied and solved .It explains the basic intension of digitalization design and manufacturing and reverse engineering important status and functions while making key spare part by oneselves.According to the characteristics of typical part of cigarette machine, summarize relevant theory and experiences of three-dimensional geometry expresses which suitable for cigarette machine part on the foundation of the figure study of computer and the theory of the computer aided geometry; research the construct method which form curve, curved surface of cigarette machine part , analyse quality and error of curved surface, and exchanging of the data between different software platforms.It mainly reserchs the key technology of digitalization design and manufacturing of typical part of cigarette machine on the foundation above basic theories.It includes : the expression method of the curve, curved surface; relevant modeling principle; editing the program which gather some point clouds of curved surface,controling of the precision of gathering point clouds; the gathering method and the treatment of some poing clouds,the modeling method of the entity and diagnosis, processing of the curved surface etc..It analyses the processing technological design of the typical part of cigarette machine and I-DEAS automatic programming system in digitalization manufacturing procession; and emulation of numerical control processing ;and optimizing of technological parameter;and programming the post file ; It mainly researchs post file with cutter complementation and mend to solve the problem which achieve the goal of altering the surplus of cutting but never processe cutter orbit file again while production. Have analysed the producing of NC program, transmition etc..It carries on instance analysis to CAD/CAM course of spare part of typical cigarette machine.It takes cam as an example,analyses the processing flow without drawing.It explains a series of course of gathering some point clouds in the whole reverse engineering ,dealting with curved surface, producing the entity model , the parameter analysis of processing, prcessing emulation , turning into processing program, the transmission of the file and Processing.It forms a set of completely system ofdigitalization design and manufacturing on the basis of reverse engineering . It establishs solid foundation for making typical spare part by oneselves, raises the use efficiency of the equipment,and reducing the cigarette production cost.
