我厂对两台CD6140A车床进行了简易数控改造遇到故障,现总结其中具有代表性的实例,供同行参考。 我厂的数控改造采用经济型数控系统,以通用486计算机作为主控部件,采用步进电机驱动,四工位电动刀架指令换刀,属双轴联动开环控制系统。 1.失步监测措施 从步进电动机的原理可知,步进电动机的失步与诸多因素有关,其中起动频率、运行频率、系统惯量、受力情况和电压波动是主要因素。由于这些因素会随工
I plant on two CD6140A lathe simple CNC transformation encountered a fault, are summarized in the representative of the examples for peer reference. CNC transformation of our plant using economical CNC system, a general 486 computer as the main control unit, the use of stepper motor-driven, four-position electric tool holder command tool change, is a two-axis linkage open-loop control system. 1. Step out of monitoring measures From the principle of stepping motor we can see that the stepper motor out of step with many factors, including starting frequency, operating frequency, system inertia, force conditions and voltage fluctuations are the main factors. Because of these factors will be with the workers
