米老鼠凸模的逆向设计与数控加工

Reverse design and numerical control machining for mickey model

逆向工程(Reverse Engineering)是近年来CAD领域最热门的研究方向之一,是一种产品的再设计和超越过程。根据米老鼠模型,运用逆向工程的方法,使用三坐标测量技术和UGS公司Imageware逆向工程软件完成米老鼠凸模的逆向三维造型设计,运用MasterCAM软件完成该模型的三维数控加工的程序编制,经实体验证、仿真加工确保无误后,进行后处理,生成数控加工代码,在立式加工中心完成模型的复杂空间曲面数控加工,体现了三维数控加工的先进性,在工程实际中具有一定的指导和借鉴意义。

Reverse Engineering is the most popular in the field of CAD in recent years,which is a process to re-design and surmount.The three-dimensional modeling of Micky is finished based on Micky Mouse＇s model,with the method of reverse engineering,by applying three coordinates measuring technology and reverse project software-Imageware provided by UGS Company.While the NC programme for the Model was proposed with MasterCAM,which later was tested and verified,simulated for processing to ensure its correction,NC code is generated after post-processing.Thus model with more complicated spatial curved surface can be machined in vertical machining center.The 3-dimension NC is proved to be an advanced processing technique and is instructive and significant in practice.
