增量式测量系统的数控机床回零的故障分析与排除

Analysis of Zeroing Fault of NC Machine Tool with Incremental Measure System and the Solution

对于采用增量式测量系统的数控机床 ,每次开机后都必须首先进行“回零”操作。本文根据数控机床回零的控制方法和动作过程 ,分别对机床回零过程中经常出现的故障进行了分析 ,如机床不能回零、回零失败、回零不准确等 。

For NC machine tool setting incremental measure system,it is essential to zero when running the machine.In this article, some zeroing faults of NC machine tool have been analysised firstly, based on the control mode and movement process of zeroing,for example, non zeroing,failure to zeroing and incorrect zeroing etc., then the reason and the removing method of the zeroing faults are also given.
