Publisher Summary Manufacturing process is the science and technology by which a material is converted into its final shape with the necessary structure and properties for its intended use. Formation of a desired shape is the major portion of processing. This chapter deals with the selection of appropriate manufacturing processes and design considerations for processing. This method of selection of processes is closely tied to the selection of material. All these factors result from collective decisions made in selecting the process-material-part combination. At this juncture of decision making, designers and engineers developing a new product already have the basic part drawing and a selection of various material-process combinations feasible for the part. The product processing could be a simple one-step operation or a combination of various processes, depending on the processability of the material used and the specifications for the finished part, which includes surface finish, dimensional tolerances, and so forth. The next stage is arriving at the material-manufacturing process combination that is technically and economically feasible. The processes are arranged by similarity of function. They can be broadly classified into three categories. Based on the desired outcome, they are primary, secondary, or tertiary processes. The taxonomy of key manufacturing processes, their classification, and specific design guidelines are discussed in detail.
