Therefore, machining process planning design is an important work, requires designers must have a rich experience in production practice and wide range of mechanical manufacturing technology basic theory knowledge. In the specified procedure, should according to the production of parts and the existing equipment conditions, taking the processing quality into account, productivity and economy requirements, after repeated analysis and parison, to determine the optimal or the best solution. Characteristics of the gearbox shell The gearbox shell process features are: the structure of plex shape。 processing plane, more than holes。 uneven wall thickness and stiffness is low。 processing of high precision typical of boxtype processing part. The main processing of the surface of cylinder block top surface, the main bearing side, cylinder bore, the main and camshaft bearing bore holes and so on, they will directly affect the machining accuracy of the engine assembly precision and performance, mainly rely on precision equipment, industrial fixtures reliability and processing technology to ensure the reasonableness. gearbox shell process design principles and the basis Design Technology program should be to ensure product quality at the same time, give full consideration to the production cycle, cost and environmental protection。 based on the enterprises ability to actively adopt advanced process technology and equipment, and constantly enhance their level of technology. Gearbox shell machining process design should follow the following basic principles: The selection of processing equipment The principle of selection adopted the principle of selection adopted the principle of bining rigidflexible, processing each horizontal machin
