摘要
本文介绍了立体仿形铣床三维进给速度的一种控制系统．在对速度量进行线性化处理后，采用运算放大器完成有关信号的运算、处理任务．该系统应用于老式机床的改造，取得了良好的效果。
A control system of 3-dimension feed speed for stereo copy milling machine is introduced in the paper.After the speed quantities are linearized,operational amplifiers are used to operate and process relative speed signals.The system can be applied to reform an old machine tool and the effect is good.
