下位TMS F2812型DSP芯片则主要用于实现复杂的插补及控制算法，并以西门子伺服驱动放大器和交流伺服电机作为驱动单元，对改造后的数控铣床各轴进行位置控制。

The lower DSP (TMS F2812) is used to realize the interpolation and control of three axes for the retrofitted CNC milling machine equipped with SIEMENS servo drive amplifiers and ac servo motors.

利用比例阀和线性光栅尺配合使用替代伺服放大器和伺服电机实现进给轴的闭环控制。

This paper give an advice that we can realize closed cycle control of feeding shaft by proportional valve and linear grid ruler instead of servo amplifier and servo motor.
