Abstract：Adjustment of engineering program in NC machining, fixture and tool for preparation and parts inspection occupied more time, affect the processing efficiency of CNC machine tools. Adapt to high precision and high efficiency of CNC machine processing requirements. Compared with the general machine tools, CNC machine tool fixture structure is simple and flexible to meet the requirements of various processing products. In view of this, combined with years of foreign works of research and application of fixture and fixture design experience, summarize the main points of fixture design in NC machining for reference.
Key words：NC machining；machining fixture；flexible；rapid exchange
