First, the workpiece can enter the automatic processing stage after the alignment and sequence debugging are completed. During the automatic machining process, the operator should monitor the cutting process to prevent abnormal cutting from causing workpiece quality problems and other accidents. The quality of the monitoring tool largely determines the processing quality of the workpiece. In the process of automatic machining and cutting, the normal wear and abnormal damage conditions of the tool must be judged by methods such as sound monitoring, cutting time control, pause inspection during cutting, and workpiece appearance analysis. According to the processing requirements, the tools should be disposed of in time to prevent the occurrence of processing quality problems caused by the failure of the tools to be disposed of in time. The tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe that performs numerical control turning processing is called a numerical control turning center. CNC machining G code can be programmed manually, but usually the machining workshop uses CAM (computer-aided manufacturing) software to automatically read the CAD (computer-aided design) file and generate the G code sequence to control the CNC machine tool.
Second, in practice, for precision parts such as precision machine tools and gyroscopes, the expected precision goals can be achieved by conservatively removing precision machining methods. Specifically, for non-ferrous metal materials, milling or turning processing methods can be used to complete the accuracy target; for ferrous metal materials, the accuracy task can be completed by the technological means of polishing, grinding, and grinding. Processing equipment is a platform for implementing precision and ultra-precision processing technology. Several factors should be considered: First, the final precision of the machine tool can achieve comprehensive accuracy; second, the machine tool data and structural design; third, the machine tool transmission and servo system; fourth, the machine tool equipment and working conditions. These factors are related to the development level of precision Dalian machining technology, which must be highly valued.
