发动机箱体形状复杂,加工特征多,尺寸及形位精度要求高,加工时间较长。在加工过程中由于刀具磨损等原因,可能造成加工尺寸超差。针对工厂一人管理多台机床的实际情况,利用宏程序控制探针移动,实现对箱体孔径尺寸的在线测量,并将实测值与公差值进行比较,当超差或宏变量赋值错误时进行自动报警,及时中止切削,避免浪费。 Engine body shape complex, multi-processing features, size and shape of the high precision requirements, processing time longer. In the process of processing due to tool wear and other reasons, may result in ultra-processing size. According to the actual situation that a factory manages more than one machine tool, the macro program is used to control the movement of the probe to realize the on-line measurement of the aperture size of the box and compare the measured value with the tolerance value when the error of the tolerance or the macro variable is wrong Automatic alarm, stop cutting in time to avoid waste.
