摘要
针对在卧式加工中心上加工多面体零件需要多次测量零偏值的问题,提出了一种新的方法,即通过测定机床的回转中心,借助AutoCAD软件,建立一个机床坐标环境,并利用一个已知的零偏值,实现快速、准确地得到其他需加工表面的零偏值。采用该方法能够减少加工中多次测量零偏值带来的繁琐工作,大大提高加工效率,降低编程的差错率。本文通过2个具体应用实例,对该方法和传统方法进行了对比,详细论述了该方法的优点及使用方法,并对其正确性进行了理论验证。采用该方法还可以应用于与卧式加工中心相似的其他设备。
Aimed at the problem of measuring the zero offset of a polyhedral part during the machining process by horizontal CNC machining center,the paper provided a new method.By determined the rotary center of the equipment and with the aid of AutoCAD tools,it can establish an equipment＇s coordinate environment.Using a know zero offset,it can get the other processing surface＇s zero offset fast and accurately.This method can reduce the tedious measurement processing,improve the processing efficiency significantly and reduce the program＇s error rate.By using two practical examples,the paper compared this method with the traditional method,discussed its advantage and about how to use in details,and validated its correctness in theory.This method can be applied to other similar equipments.
