该功能可以使数控系统根据刀尖所处的X坐标值，作为工件的直径值来计算主轴转速，使切削速度保持恒定。

This function can make numerical control system according to the point in the X coordinates, as the diameter of the workpiece calculated value spindle speed, and the cutting speed to be constant.

也还存在其它一些变量影响表面切削速度的最佳值。

There are also other variables that affect the optimal value of the surface cutting speed.

该模型以切削力恒定和较高的金属去除率的模糊综合值作为目标函数，找出了最佳切削用量。

In this model, the fuzzy comprehensive evaluation of the fixed milling force and higher metal removing rates is used as the objective function so that the best cutting parameters are gotten.
