G19:选择 YZ平面。 Codes G94/G95〔cutting feed〕 G94/G95〔进给速度〕 Feed rate of linear interpolation, circular interpolation etc., are commanded with numbers after the F code. 直线插补、圆弧插补等的进给速度是用F后面的数值指定的。 Codes G94 specifies the amount of feed of the tool per minute, G95 specifies the amount of feed of the tool per spindle revolution. G94后面的F值指定每分钟的***进给量,G95后面的F值指定主轴每转的***进给量。
