在先进的制造技术中，需要改进金属切削过程的建模和仿真。采用三维全热-力耦合有限元模型对高速铣削TiAl6V4钛合金的切削温度进行了仿真分析。对刀具和工件的温度分布进行了预测。研究了铣削速度和径向切削深度对刀具最高切削温度的影响。结果表明：铣削热只影响加工表面片层温度的升高；刀具的最高温度随着径向切削深度和铣削速度的增加而增加，在速度为60 m/min时为310°C，在速度为400m/min时增加到740°C。最高温度仅在切削刃的集中区域有效，最高温度的位置远离刀尖，以获得更高的径向铣削深度。预测的切削过程温度分布与文献中给出的实验结果一致。研究结果为进一步了解TiAl6V4钛合金的热挤压加工机理提供了基础。
mprovements in modeling and simulation of metal cutting processes are required in advanced manufacturing technologies. A three dimensional fully thermal mechanical coupled finite element model had been applied to simulate and analyze the cutting temperature for high speed milling of TiAl6V4 titanium alloy. The temperature distribution induced in the tool and the workpiece was predicted. The effects of the milling speed and radial depth of cut on the maximum cutting temperature in the tool was investigated. The results show that only a rising of temperature in the lamella of the machined surface is influenced by the milling heat. The maximum temperature in the tool increases with increasing radial depth of cut and milling speed which value is 310°C at a speed of 60 m/min and increases to 740°C at 400m/min. The maximum temperature is only effective on a concentrated area at the cutting edge and the location of the maximum temperature moves away from the tool tip for higher radial depths of milling. The predicted temperature distribution during the cutting process is consistent with the experimental results given in the literature. The results obtained from this study provide a fundamental understanding the process mechanics of HSM of TiAl6V4 titanium alloys.
