铣刀片温度场数学模型的研究

Study on the Mathematical Model of Temperature Field of Milling Cutter

铣刀片作为机械切削过程中应用最为广泛的一种刀具,它的使用寿命直接反映了切削水平的高低,切削过程中产生的温度场是破坏刀片的最主要原因之一.本文通过人工热电偶法获得刀片上6个点的温度,根据热传导定律推导刀片切削过程中的温度场数学模型,使用此模型来研究切削过程中温度的变化情况,为研究更有效的切削刀具提供数据支撑.

As one of the most widely used cutting tools in the process of mechanical cutting,the service life of milling cutter directly reflects the level of cutting. In this paper,the temperature of six points on the blade is obtained by the manual thermocouple method,and the mathematical model of the temperature field in the cutting process of the blade is deduced according to the law of heat conduction.
