摘要：

The surface beat fluxes on the cutting edges of cutting tools are estimated in the present three-dimensional inverse heat conduction problem. The inverse algorithm utilizing the steepest descent method (SDM) and a general-purpose commercial code, CFX4.4, are applied successfully in this study in accordance with simulated measured temperature distributions on tool surfaces by infrared thermography. Two different tool shapes are used to illustrate the validity of inverse determination of the unknown heat fluxes with different measurement errors. Results of the numerical simulation show that reliable estimated heat fluxes can be obtained by using the present inverse algorithm.
