端面铣削最佳切削速度是由保证最低工序成本的“经济”切削速度v_0和刀具相对线性磨损强度为最小的切削速度v_0来确定的。以前的计算方法既繁重,又不经济,且在使用上有一定的局限性。本文从刀具尺寸耐用度的金属切削特征对给定的一对被加工材料和刀具材料来说,是最佳切削温度常数和最小切削分力这一原理出发,利用切削金属时机械能和热能的平衡方程式,得到确定切削速度v_0的理论关系式。由于速度v_0可从其与速度v_0的固定比值中求出,因而只要计算出速度v_0,就可求出端面铣削的最佳切削速度,大大地减小了计算工作量。
The optimum cutting speed for face milling is determined by the “economic” cutting speed v_0 which guarantees the lowest process cost and the cutting speed v_0 where the relative linear wear strength of the tool is the minimum. The previous calculation method is not only cumbersome, not economical, and there are some limitations in the use. In this paper, the metal cutting characteristics of the tool size durability for a given pair of material and tool material for cutting, the optimal cutting temperature constant and the minimum cutting force of this principle, the use of cutting metal mechanical and thermal balance Equation, get to determine the cutting speed v_0 theoretical relationship. Since the velocity v_0 can be obtained from the fixed ratio of the velocity v_0 to the velocity v_0, the optimum cutting speed of the face milling can be obtained as long as the velocity v_0 is calculated, which greatly reduces the calculation workload.
