SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING Often there exist alternatives of process plans for manufacturing a part. The quality of a process plan should be evaluated from a technological as well as an economical standpoint. A good process plan not only ensures the required quality of manufactured parts, but also reduces the production cost. In process planning, a comprehensive analysis of part structure, material and technical specifications, production volume and manufacturing conditions must be made, so as to properly make all the decisions related to the planning of the process Many decisions should be made in machining process planning Selection of the blank and its manufacturing method Selection of machining methods for part sur faces Determination of operations sequence Determination of workpiece setting method for each operationSCIENCE AND TECHNOLOGY ENGLISH FOR MECHANICAL ENGINEERING Often there exist alternatives of process plans for manufacturing a part.
