The product design is the plan for the product and its components and subassemblies. To convert the product design into a physical entity. a manufacturing plan is needed. The ac tivity of developing such a plan is called process planning. It is the link between product design and manufacturing, Process planning involves determining the sequence of pro ccssing and assembly steps that must be accomplished to make tile product In the present chapter, we examine process planning and several related topics.

At the outset, we should distinguish between process planning and production planning, which is covered in the following chapter, Process planning is concerned with the engineering and technological issues of how to make the product and its parts. What types of equipment and tooling are required to fabricate the parts and assemble the product? Production planning is concerned with the logistics issues of making the product. After process planning has determined the technical details, production planning is concerned with ordering the materials and obtaining the resources required to make the product in sufficient quantities to satisfy demand for it.
