The following areas: design of transmission of the table, mainly the use of ball screws; the overall structure of the design table to understand the strengths and weaknesses, take full account of the principal contradiction, merit-based selection; control system design, its applications become more familiar with the Stepper motor-driven feed location can be accurate but the drawback is the lack of output power, so consider the source of the hydraulic motor as the driving force and the stepper motor drive system into the compound, hydraulic feeding Although it is impossible to locate, but with high output power, the two complement each other, so that accurate feed motion can be stable.

有以下几个方面：工作台的传动机构设计，主要是滚珠丝杠的运用；工作台整体结构的设计，了解优缺点，充分考虑主要矛盾，择优选取；控制系统的设计，进一步熟悉其应用步进电机驱动进给可以进行准确的定位但有个缺点就是输出力不足，所以考虑将液压电机作为动力源与步进电机驱动进给系统复合，液压进给虽然无法进行定位，但具有高输出力，二者优势互补，使进给运动可以准确稳定的进行。

Direction of the feed motion n.

进给方向，进刀方向

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。
