1.
In the case of keeping the longevity of the NC cutter,the author did some experiments to fix the NC milling parameter which can bring a higher metal cutting rate and tried to establish the proportion among the NC cutter diameter,cutting depth,cutting width,feeding velocity and spindle speed.
针对数控铣削参数的选择进行定量地讨论,在保证实际刀具寿命条件下,通过少量试验快速确定具有较高金属切除率的铣削参数,意在建立刀具直径与切削深度、切削宽度、进给速度和主轴转速等铣削参数的比例关系。
补充资料：车削时进给量与刀尖半径粗糙度的关系
车削时，刀尖半径与进给量、表面粗糙度的理论值存在一定关系，我们选择进给量时一般不应超过此值。
h=re-(re²；-(0.5×f)²；)0.5
h为残留高度，而：
Ra=(0.25~0.33)h
因此:
fmax=(Ra×re/50)½；
h为残留高度，而：
因此:
