| Abstract: | The cutting temperature concerns about the tool wear,machined surface integrity and machining precision.Its variation rules reflect an important character of high-speed machining.By using numerical simulation,the effect of cutting speed,feed and cutting depth on dynamic characteristics of cutting temperature on chip,workpiece and tool are revealed in the paper.The variation rules of cutting temperature with cutting speed,feed and cutting depth are concluded.The results are significant for optimizing process parameters and building database on high-speed machining. |
