Heat sources and fluxes in milling: Comparison of numerical, analytical and experimental results

The paper describes the comparison of numerical solution, analytical approach and experimental results calculating heat sources and heat fluxes in a milling process with the aim of the calculation of the temperature distribution. Analytical solutions for standard geometries are superposed in order to represent the tool best possible. Exposed with the heat sources calculated by finite element simulation of the interrupted chip formation process the solution of these analytical representation is compared with numerical ones. These have been investigated in previous research on a consistent numerical simulation method for calculation of heat sources and fluxes in milling. Both models are fitted and verified by cutting experiments.
