As the automation production capacity increases, appears in the modern factory requires a combination of machine tools more and more, combined machine tool is based on a generic part, together with the private part of a specific shape and process design of workpiece and clamp, consisting of semi-automatic or automatic machine. It generally uses multiple axes, knives, multistep, faceted or multi-station simultaneous processing of production efficiency, higher than the General machine tool several times to the dozens of times. Due to the generic part has standardized series, flexible configurations, as needed, to shorten the design and manufacturing cycle. Therefore, the advantages of modular machine tool both low cost and high efficiency, are widely used in mass production, and can be used to form the automatic production line. In this design, based on a full analysis of the relevant data, based on structure features of machine parts, machining parts size precision, surface roughness requirements and positioning clamp method, processing methods a
