Description

数控是数字控制的简称,数控技术是利用数字化信息对机械运动及加工过程进行控制的一种方法。
早期时有两个版本:
NC(Numerical Control):代表旧版的、最初的数控技术。
CNC(Computerized Numerical Control):计算机数控技术——新版,数控的首选缩写形式。
NC可能是CNC,但CNC绝不是指老的数控技术。
早期的数控系统是由硬件电路构成的称为硬件数控(Hard NC),1970年代以后,硬件电路元件逐步由专用的计算机代替而称为计算机数控系统,一般是采用专用计算机并配有接口电路,可实现多台数控设备动作的控制。因此现在的数控一般都是CNC(计算机数控),很少再用NC这个概念了。

数控技术

数控车床进给加工路线指车刀从对刀点(或机床固定原点)开始运动起,直至返回该点并结束加工程序所经过的路径,包括切削加工的路径及刀具切入、切出等非切削空行程路径。数控技术也叫计算机数控技术(CNC,Computerized Numerical Control),它是采用计算机实现数字程序控制的技术。这种技术用计算机按事先存贮的控制程序来执行对设备的运动轨迹和外设的操作时序逻辑控制功能。由于采用计算机替代原先用硬件逻辑电路组成的数控装置,使输入操作指令的存贮、处理、运算、逻辑判断等各种控制机能的实现,均可通过计算机软件来完成,处理生成的微观指令传送给伺服驱动装置驱动电机或液压执行元件带动设备运行。
