【摘要】 本文采用红外热成像技术检测了切削刀具温度分布,给出了多种工件材料、刀具材料及切削速度等条件下切削刀具的温度场;还研究了后刀面磨损量与刀具最高温度值及其分布特征之间的关系。试验表明:此技术可以快速、直观、非接触、较精确地在线实时无损监测切削温度,为选择最佳切削工艺参数、提高零件表面质量及刀具寿命提供依据。更多还原

【Abstract】 The temperature distribution in a tool is determined by using infraredthermography method for different work materials, tool materials and cuttingspeeds. The relationships between the flank wear and the cutting tempera-turedistribution are studied. The experiment results show that infrared thermographytechnique can be used to determine the temperature distribution in tool onlinerealtime, and it has the advantages of good visibility, non-contact and accuracy.The temperature distributions in the tool during cutting can be considered as ascientific basis for selecting optimum technical parameters and improving worksurface quality and increasing tool life.更多还原
