摘要随着缸盖零件的加工要求越来越高，数控机床在缸盖零件加工中起到的作用也越来越重要。当数控加工程序编制完成之后，在进行正式的零件加工之前，需要对加工程序进行正确性检验。如果编制完成的数控加工程序中存在错误，可能导致工件过切或者欠切、刀具和零件、刀具和夹具、刀具和工作台之间的干涉和碰撞等问题。随之而来的是越来越多的数控机床仿真软件，但是用于数控加工工艺仿真系统的软件却很少，目前VERICUT在这方面是功能最完善的软件，将VERICUT应用于对缸盖零件加工前对程序进行验证对缸盖加工具有重要的意义。53207

本课题针对该缸盖零件结构特点进行了深入研究，利用Pro/E和VERICUT软件功能，提出了基于虚拟制造环境的缸盖零件加工工艺设计与仿真方法。首先对缸盖零件加工工艺设计，然后利用VERICUT软件构建虚拟制造环境以及选取缸盖铣各侧面并钻镗四周孔加工工序进行仿真加工，并且对仿真结果进行比较检查，利用软件自动比较功能，分析缸盖加工是否存在过切或者残留。通过利用计算机虚拟仿真技术，从根本上改变了对制造资源的依赖性，同时允许修改和快速重置虚拟模型，在这个虚拟模型中，产品的加工时间减少了，降低成本，并能及早发现和暴露实际加工中可能隐藏质量问题，这对缸盖加工具有重要的意义。

Abstract

With the cylinder head machining increasingly demanding, CNC machining parts to play in the cylinder head is also an increasingly important role. When programming is complete CNC machining, during the formal parts processing required before machining program correctness test. If you complete the preparation of the NC machining program errors that may lead to under-cut or gouge the workpiece, tool and spare parts, tools and fixtures, tools and workbench interference and collision between the issues. Followed by a growing number of CNC machine simulation software, but for the CNC machining process simulation system software is rarely present VERICUT in this respect is the most sophisticated software, VERICUT will be applied to the cylinder head parts validated before processing the program processing of the cylinder head has an important significance.

The topic for the head part structural features in-depth study, the use of Pro / E and VERICUT software features is proposed based on virtual manufacturing environment head parts machining process design and simulation methods. First, head parts processing technology design, then use VERICUT software to build a virtual manufacturing environment and select the cylinder head milling and drilling boring four weeks each side hole machining process simulation processing, and the simulation results are compared inspection, the use of software to automatically compare function analysis cylinder head machining overcut or whether there is residual.

Through the use of computer virtual simulation technology, fundamentally changing the dependence on manufacturing resources, while allowing rapid modification and reset the virtual model, in this virtual model, the product reduces the processing time, reduce costs, and can be detected early and actual exposure may be hidden in the quality of processing, which has an important significance machining head.
