Through the combination of mechanical design and 3D drawing software, the design process of CAD/CAM easier to manage and control the realization of saving time, greatly help to realize the automation of design and machining, improve the machining precision and quality, shorten the product development cycle. The pump body is more and more widely used in the mechanical industry, but the pump body is difficult to process, and its process performance is poor and the processing technology has not been improved. Therefore, the processing technology of D6114ZQB pump were analyzed, firstly the rough part selection, and design the process, determine the fixture scheme and on the selection of locating datum, determine the machining allowance, process size and blank size, and to determine the cutting allowance, and make the process of formulation plus processing scheme, process. The processing of D6114ZQB pump body is always a difficult question, most of the pump body is processed according to the processing experience of master manufacturing, and processing efficiency is ve
