基于UG和VERICUT的塑料模嵌件数控加工

摘要

In plastic mould,the processing of inserts is common processing content.In order to meet the forming requirements of the product and the structure of the mould,Steep curved surfaces and some deep cavity structures often appear on the embedded parts,which make it difficult to write the NC programs by the traditional manual programming,and caused a certain difficulty to parts processing.Aimed at the structure and processing diffi-culties from plastic mould insert,The automatic programming and processing of insert based on UG was researched,and the simulating manufacturing of parts based on VERICUT was taken in this paper,check the over cut and lack cut in the processing,to avoid the collision and interference existing in the actual processing,provided some reference and feasibility for the NC machining and actual production of complex insert parts.%在塑料模中,嵌件的加工是常见的加工内容.为满足产品的成型要求和模具的结构要求,嵌件上经常会出现陡峭的曲面及一些深腔结构,采用传统手工编程很难实现零件的NC程序编写,这给零件的加工造成了一定难度.针对某塑料模嵌件的结构及加工难点,研究基于UG的嵌件类零件自动编程加工,并基于VERICU T 仿真平台对零件进行仿真加工,查看加工中零件的过切、欠切情况,避免了实际加工中存在的碰撞、干涉等情况.
