建立了自走丝式回转刀具(SPRT)加工淬硬钢的刀具温度分布模型。针对刀具寿命受切削温度影响较大的问题，建立了回转刀具车削淬火52100钢(58HRC)时的换热及温度分布模型。该模型基于导热的运动热源理论，采用有限元方法进行求解。利用红外热像仪测量了不同切削条件下刀具的温度分布，对模型进行了实验验证。最后，根据产生的刀具温度，比较了旋转刀具和等效定向刀具的切割过程。(C)2004爱思唯尔有限公司。保留所有权利。
This paper addresses modeling of the tool temperature distribution in self-propelled rotary tool (SPRT) machining of hardened steels. Since tool life is significantly influenced by cutting temperatures, a model is developed to analyze the heat transfer and temperature distribution in rotary tool turning of hardened 52100 steel (58 HRC). The model is based on the moving heat source theory of conduction and employs the finite element method (FEM) for its solution. The model is experimentally verified through measurements of the cutting tool temperature distribution using ail infrared camera under different cutting conditions. Finally, both rotary and equivalent fixed tool cutting processes are compared in terms of cutting tool temperatures generated. (C) 2004 Elsevier Ltd. All rights reserved.
