数控机床光电输入机是控制部分中的薄弱环节之一。据统计,数控机床在加工时,因轨迹走错而造成工件损坏的故障中,有百分之七十以上是由于光电输入机的误读而引起的。光电输入机的故障一般均造成轨迹走错,工件损坏,有时还会造成刀具、工夹具、甚至机床的损坏。为了保证数控机床的可靠性,首先必须提高光电输入机的可靠性,排除因光电输入机的 CNC machine optical input machine is one of the weak links in the control section. According to statistics, in the processing of CNC machine tools, due to errors in the track caused by workpiece damage damage, more than 70% is due to misinterpretation of the photoelectric input machine. Photoelectric input machine faults are generally caused by the wrong track, the workpiece is damaged, and sometimes can cause the tool, jig, and even the machine damage. In order to ensure the reliability of CNC machine tools, we must first increase the reliability of the optical input machine, excluding the optical input machine
