数控系统比例缩放功能的应用难点分析

Difficult Analysis of Application based on Proportional Scale Function

数控系统的比例缩放功能应用难点,是缩放比例的正、负号确定及缩放中心坐标的计算。针对同向、反向及镜像三种情况,分别分析了符号的确定方法和与缩放中心坐标计算的技巧,对于手工编程具有借鉴作用。

Application Difficult is mark determination of proportional scale and calculation of center coordinate in NC proportional scale function.On three condition of coottrrent,reverse and mirror image, Analysis its mark determination method and calculation skill of center coordinate.It is profits from the significance for manual programming.
