摘要
作为国际标准试件中的新成员,S形检测试件由于其造型复杂,一直是加工领域中的一个难题。在UG NX环境下,通过三维建模、工艺规划、数控编程得到了S形件加工后置指令。基于虚拟机床技术理论,搭建了后置指令加工仿真通用平台,并验证了S形件数控程序的准确性。提出并对比分析了多种编程加工方法下S形件的理论误差。选取最优编程方法进行切削实验,实现了S形件的五轴联动加工。
As a new member of international standard specimens,＂S＂shape detection test piece became a problem in the processing area due to its complex shape.In the environment of UG NX,through some operations such as three-dimensional modeling,process planning,CNC programming,＂S＂piece post processing commands were derived.Based on virtual machine tool theory,a machining simulation universal platform was set up,and the accuracy of processing program was verified.A variety of methods of five-axis CNC programming were adopted,and theoretical errors of various programming methods were compared through the simulation platform.The post commands with minimum theoretical errors were selected to cutting experiments,they realized five-axis machining of＂S＂piece.
