Definition

In metal cutting processes, almost the entire mechanical energy is converted into heat. Sources of heat are the primary shear zone and secondary shear zones at the rake and flank face. Heat partitioning describes the fractions of heat dissipated by the tool, the workpiece, the chips, and the cutting fluid.

Theory and Application

Models on Heat Partitioning

Heat partitioning directly affects tool wear and surface integrity of the machined part. Therefore researchers have been aiming to predict it by different modeling and simulation techniques. One prominent approach is to utilize the moving heat source theory (Jaeger 1942) as an approximation for the stationary chip formation process. This kind of analysis enables a process description based on first physical principles. An excellent compilation and detailed discussion of models for the heat partitioning at the primary shear zone in orthogonal cutting is given by Komanduri and Hou (2000). The most important information of...
