附录 Process Planning The product design is the plan for the product and its components and subassemblies.To convert the product design into aphysical entity ,a manufacturing plan is needed .The activity of developing such aplan is called process planning .It Process planning is the link between product design and manufacturing .involves determining the sequence of processing and assembly steps that must be accomplished to make the product .In the present chapter ,we examine processing planning and several related topics. At the outset ,we should distinguish between process planning and production Process planning planning ,which is covered in the following chapter. is concerned with the engineering and technological issues of how to make the products and its parts. What types of equipment and tooling are required to fabricate the parts and Production planning assemble the product ?is concerned with the logistics of making the product .After process planning is concerned with ordering the materials and obtaining the resources required to make the product in sufficient quantities to satisfy demand for it. Process Planning Process planning involves determining the most appropriate manufacturing and assembly processes and the sequence in which they should be accomplished to produce agiven part or product according to specifications set forth in the product design documentation.The scope and variety of processes that can be planned are generally limited by the available processing equipment and technological capabilities 1
