From the perspective of processing operation process, NC machine tool processing can be divided into three modules: programming, tool setting and automatic processing. Among them, programming and tool setting are preparatory work for machining operations. Whether the programming is correct, whether the selected cutting parameters are reasonable, and whether the input of tool setting parameters is accurate will be shown in practical machining. Therefore, in order to ensure the accuracy of the processing operation of the NC machine tool, it is usually necessary to stop the trial processing, so as to test whether there are problems in the automatic processing of the NC machine tool. In the trial processing, strictly following the processing principle of “three looks, two needs, and one stop” can greatly reduce the collision problem in the operation of the machine tool.<\/p>
