It is the solid axis that transmits torque between the differential mechanism and the driving wheel. Its inner end generally connects by integral-key and semi-axis, outside end connects with hub. The parts have transmission in machinery and equipment. When performing the machining process analysis and programming design of automobile semi-axes, it bases on mechanical manufacturing process design. Use the method of collect research, analysis of extraction and case study with analyzing manufacturability of semi-axis in detail to design manufacturing process. The process design of semi-axis parts should try its best to reduce the cost of processing and the intensity of workers. According to the requirements of the processing of half axle design special jig, mainly used for drilling half axle disk evenly distributed in the design of holes, the economy and practicability attention fixture. Automobile semi-axes machining process analysis for enterprises engaged in production of automobile half shaft is very important and technology will have a direct impact on the efficiency and quality of machining precision and processing. Reasonable processing route will not only ensure the quality of parts and enterprises can make full use of existing equipment and mak
