Energy Consumption Modeling of Machining Processes

Energy consumption management is an effective tool for adapting the production system under the conditions of changing the operating mode. Rational energy consumption improves not only the energy performance of the enterprise but also the ecological and general economic parameters. Energy consumption assessment of each technological operation and for each workplace requires all production facilities (equipment, materials, operations, etc.) to be clearly identified. This study represents machining operations as the transformation of workpiece's surface into the desired surface of the part. This is important in order to evaluate its effectiveness in terms of energy conversion. This approach serves as the basis for mathematical modeling of machining operations' energy consumption, which considers the type, parameters, and time of exposure. This information is obtained from the control program text at the preparatory stage by means of syntactic and lexical analysis. This chapter presents a planned schedule of the machine tool's energy consumption during the processing of a given surface. A processing experiment, performed on real equipment, helped to obtain a graph of actual energy consumption. Finally, the paper discusses efficiency strategies that can be used at some hierarchical levels of an industrial enterprise.
