According to the original material to clamp the mouth parts activities machining process planning and special fixture design. Through the design and study of manufacturing activity, a whole, the panorama of understanding and grasp, to master the basic rules of the metal cutting process, and master the basic knowledge of mechanical processing, can choose processing method and machine tool, cutting tool, fixture and processing parameters, have the ability of making process planning and control of the machine machining precision and surface quality of basic theory and basic knowledge, preliminary analysis and solution of the ability of the process on site. By using UG design parts, learned about the processing parts for the use of equipment, tooling and machine cutting movement for process planning design, including the blank, and determine the selection, the process route, machinery processing etc, and make the process card.
