Abstract：The process is the base of frock design、manufacturing、the method of machining and machining route. Its function is flowing: organizing produce， controlling quality， enhancing productivity， reducing cost， reducing produce periods， improving work conditions， etc. So， the process planning is the core part of produce. Fixture is very important equipment in process of machine manufacturing because it can directly affect the quality of products and productivity and cost. So fixture designing is also a basilica portion in machine process preparative and manufacture. This thesis is about the analysis with the craftwork and the structure of the 2105 speed governor tray which is used for the diesel engine， make sure the process route， establish the foundry process project and the process planning of the parts， and design a set of appropriative fixture for the bore with diameter 10mm.
Key Words：Group technology; Foundry technology; Process planning; Fixture design
