摘要：

Thermal boundary conditions in metal cutting are of major significance for the credibility of thermal models. Relevant boundary conditions need to be defined at the characteristic regions of metal cutting: the shear zone, the contact zone of chip and tool, the clearance face and the work piece surface. In this contribution, the experimental investigation of the thermal boundary conditions at these characteristic regions is presented. The boundary conditions were investigated by detailed analysis of infrared thermal images. Different materials and cutting parameters were investigated. From the investigation heat source strengths and heat partition ratios were yielded. (c) 2016 The Authors. Published by Elsevier B.V.
