设计仿形铣床进给伺服系统会面临这样一些问题，例如根据机床工艺要求如何确定进给伺服系统的设计依据？实现２Ｄ仿形都有那些基本控制规律？不同的控制规律对于控制系统的数学模型有何影响？按照基本控制规律怎样去构成系统（系统的结构设计和参量的计算）？ＸＢ ４４５０ Ａ仿形铣床进给伺服系统的设计探讨了上述问题，使机床进给采用普通丝杆传动在速度为２１０毫米／分的情况下，仿形精度达到± ０． ０２７５毫米。
Design Copying milling feed servo system will face such problems, for example, according to the requirements of the machine tool to determine the design basis of the feed servo system? 2D contours to achieve those basic control laws? What is the influence of different control laws on the mathematical model of the control system? In accordance with the basic rules of control to form a system (system structure design and parameter calculation)? XB 4450 A profile milling feed servo system design discussed the above problems, the machine feed using ordinary screw drive at a speed of 210 mm / min, the profiling accuracy of ± 0. 0275 mm.
