数控冲床手册（CNC punch press manual） NC punching, programming, analysis, processing With the development of stamping equipment, with more and more CNC punching process characteristics, through the research and analysis of CNC punching, and puts forward some matters needing attention in the program design of CNC punching in, and with the corresponding examples illustrates specific methods to complete the work. The author of the article has very rich practical experience, because these articles are very practical. CNC punch press is pre programmed in accordance with processing, punching processing equipment for sheet metal automatically. The ideal machining program should not only ensure the qualified parts to meet the design requirements, but also make the CNC punching machine get a reasonable application and make its performance fully play. For NC programming, either manual or automatic programming, the programming before going through the process analysis of the parts processing, and then to make the process reasonable process scheme, but also to choose a suitable mold and processing speed. In the design of NC program, more attention should be paid to some programming techniques. If we ignore some technical details, sometimes even if the processing program is correct, but because the process procedure is not reasonable, also cannot produce the qualified parts, what is more, will cause the alarm and damage the machine. This article will analyze the common problems in the NC punching program, and give the corresponding solutions to the specific problems. Two NC punching program design process analysis 1. select the appropriate programming benchmark CNC punching machine in processing, are based on the origin of the machine tool for positioning benchmark, in general circumstances, but also to this benchmark for programming standards. But sometimes choose the appropriate programming reference, can greatly reduce the numerical calculation in the design process, reduce the work
