| 摘 要： | 在切削金属过程中所消耗的能量几乎９０％以上都转化为热，致使工件，切屑和刀具的温度都上升，其中刀具的温升与切削机理及切削参数密切相关，并且直接影响刀具磨损及其全用寿命。为了研究陶瓷刀具切削温度分布对其磨损规律和机理的影响，根据传热理论建立了数学模型，用计算机模拟编制出陶瓷刀具切削区温度场计算的专业软件，可以得出不同陶瓷料刀具在不同切削条件下切步同工件材料过程中的温度分布曲线图，而且实际测量值与模拟值

| Abstract: | The temperature distributions on the surface of Si 3N 4 and Ti(CN) ceramic cutting tools for turning different metallic materials were computed and plotted by using computer simulation based on a mathematic model of heat sources. The results showed that the temperature on the rake face of ceramic cutting tools for turning 18 8 stainless steel was much higher than turning 1045 plain carbon steel due to the much lower thermal conductivity of the former, and it was increased |
