In this system the motion controlling centers upon regulating the speed of wire feeding and movement of lead screw in each direction.Four motors separately drive the wire-feeding tape roll and the lead screw move respectively following their directions of X, Y, Z axis. If all the motors are controlled by 89C51 directly,it will rise great difficulty for software and hardware implementation. So the suggested solution is to combine the microcomputer with stepper motor driver and control of their motion.

在本系统中运动控制的关键即送丝与各丝杠移动的调节，由四个电机分别驱动X，Y，Z轴方向的丝杠行走以及送丝操作，运动控制部分如果用89C51直接驱动各电机则在软件和硬件实现上都比较困难的，所以选用单片机与步进电机驱动器结合起来控制它们的运动。
