This section is a shell of supporting and embracing transmission mechanism. In the design, it should first process the structural and industrial analysis of the section, and then determine the coarse benchmark, fine benchmark, machining allowance and blank size of the section to obtain the process of the parts making. After that it calculated the cutting dosages of every process and the prod
