对数控铣削加工中的顺铣和逆铣的特点进行系统的阐述,正确选择顺铣与逆铣可有效提高表面加工质量,只有分清顺铣和逆铣才能合理选择左右刀具半径补偿指令G41和G42。
The characteristics of down-milling and down-milling in CNC milling process are systematically described. The correct choice of down-milling and up-milling can effectively improve the surface processing quality. Only through clear-cut milling and up-milling can a reasonable choice of left and right tool radius compensation commands G41 and G42 .
