CAPP-CNC系统的研究

A Study on CAPP- CNC System

本文主要介绍CAPP-CNC系统及其工作原理。通过计算机把CAPP输出符合要求的零件加工工艺规程信息自动生成相应的CNC指令块,经过有效处理形成CNC指令系列,再通过串行通讯技术直接输入CNC机床,实现数控机床加工自动化。

This paper presents a CAPP(Computer Aided Process Planning)-CNC (Computer Numerical Control) system and introduces its working procedure. The imformation of the process plan of the workpiece outputed from the CAPP is quickly translated into the CNC program. Then the CNC program can be directly transmitted to the CNC machine tool by the asynchronous data communication and automatic machining can be put into action.
