Energy - Information Regularities of Increasing Productivity in Metalworking Machine Tools

Abstract

Increasing productivity by higher cutting speed and achieving high precision of machined products at the same time is an important trend in the development of manufacturing technologies and metalworking machine tools. If the traditional method of exchangeable components in assemblies will lead to inefficient precise processes, the product costs will increase. The proposed energy-informational model considers a procedural system establishing the ratio of the cutting speed and the speed of physical processes in the machine tools. The energetic limit for the attainability of associated processes describes the allowable speed of materials processing by the machine tools. Stiffness of machine tool structures for highest precision manufacturing becomes comparable to work piece geometrical accuracy and manufacturing process tolerances. This paper gives several examples for admissible limits of increased productivity by increased process speeds in various manufacturing technologies for both traditional cutting and innovative methods.
