NC=Numerical ControlFor example NC shoud be adopted whenever there is similar raw material and work patrs are produced in various sizes and complex shopes.Those production shops that may have frequent changeovers will surely benefit from NC programs.It's better to use NC tools together with other technical advances, such as programmed optimization of cutting speeds and feeds, work positioning, tool selection, and chip disposal. 数控=数值控制 例如数控,应通过每当有类似的原料和工作patrs生产在不同大小和复杂肖普斯。 那些生产的商店可能有频繁的转换,必将有利于从数控程序。 它的更好的使用数控工具连同其他技术进步,如程序的优化切割速度和饲料,工作定位,刀具选择,以及芯片处理。
