主动检验,一般指在加工过程中对工件进行检验,并根据其检测数据处理的结果,对机床实行某些控制,以防止废品产生,确保加工质量,提高生产效率。本文对于一种光学扫描方法,提出了数字控制的逻辑原理。文中首先介绍了一种大直径的光扫描法检测原理,然后讨论了定时测量的采样器、比较器与逻辑判断、进退刀的控制方法与进退量的逻辑控制原理、以及几个控制门的逻辑设计等。
Active inspection, generally refers to the processing of the workpiece inspection, and based on the results of the test data processing, the implementation of some control of the machine to prevent waste generated to ensure processing quality and increase production efficiency. In this paper, an optical scanning method, the logic of digital control logic. First of all, a large-diameter optical scanning method is introduced in this paper. Then, the principle of sampling control, comparator and logic judgment of timing measurement, the control method of advance and retreat and the logic control principle of the advance and retreat amount are discussed. Design and so on.
