Abstract

Manufacturing industry is energy intensive. Due to the increasing energy cost and upcoming energy and environmental regulations, manufacturing faces the challenge of improving energy efficiency. This chapter gives an overall review of energy consumption in various manufacturing processes. The basic concepts of power, energy, and work are introduced. The scope and boundary of energy accounting are also discussed. The energy for a unit manufacturing process is classified into four parts: processing energy, machine tool energy, process periphery energy, and background energy. Case studies on processing energy modeling in forging, orthogonal cutting, grinding has been provided. The relationship between specific energy and material removal rate has been investigated. In addition, the measurement of power and energy consumption in manufacturing is discussed. Furthermore, possible energy reduction strategies are discussed.

2.1 Unit Manufacturing Processes

Manufacturing involves the controlled application of energy to convert raw materials into finished products with defined shape, structure, and properties that satisfy given functions. The energy applied during processing may be mechanical, thermal, electrical, or chemical in nature. ...
