推导了五坐标端铣数控加工中的后跟角计算公式，提出了后跟角的优化计算方法——刀盘周边7点干涉检验法，分析了各种加工误差，提出了刀轴摆动误差补偿方法——刀具切触点偏置法，给出了走刀步长、切削宽度以及刀轴摆角的计算公式。

The feed motion is projected into each feed axis, and based on its mechanical model(motor driving torque/force, Inertial force and cutting force), the constraint relationship between feedrate, feed acceleration, and feed drive capabilities and toolpath geometric characteristics is derived. With this constraint model, the acceleration and deceleration of each axis can be limited within its capability.

将进给运动分解到各运动轴，根据机床进给轴的力学(电机驱动力／力矩、进给系统所受的惯性力及切削力)模型，推导了多轴联动加工时进给速度、加速度与各进给轴驱动能力以及加工路径几何特性之间的约束关系，使得加工过程中机床各运动轴的加减速始终处于其加工能力范围内。
