Abstract

This chapter introduces readers to assembly processes and methods and the energy these operations consume. Assembly is the realization of a product that has progressed through design, redesign, testing, and component manufacturing. It is the culmination of work by designers, engineers, machinists, and others required to produce high quality, functional products quickly enough to meet demand. This chapter introduces energy use in assembly operations as it relates to energy efficient manufacturing. Energy consumption analyses have the potential to influence assembly workstation design, material handling, and part locating, as well as upstream fastener design or selection decisions.

Energy consumption in assembly operations is described though (1) introducing assembly systems and process, (2) classifying assembly energy consumption and discussing joining methods, (3) measuring and assessing energy consumption of assembly systems, and (4) an actual case study from automotive manufacturing. Rivets, welds, screws, and snap-fits are some of the joining methods discussed in the chapter. Gross and fine assembly motions are discussed in terms ...
