What is the difference between the GTA rotating coordinate system and the G15 polar coordinates?
The XY axis is fixed according to the rotation of the XY axis.
Simple explanation, G68 is based on drawings or workpiece processing needs, your XY axis according to the value of R after all the rotation, after the rotation of the XY axis is no longer horizontal and vertical, but the rotation of the angle. G16 rotation is
G68 polar coordinate rotation, format G68 X_ Y_R_ (XY is the rotation point of the center point) R is the angle formed by the X axis, it is counterclockwise, negative is clockwise. After use, the program must add G69
For example, G68 X0Y0R45. Is to X0Y0 as the center, the XY axis counterclockwise rotation of 45 degrees, if behind this procedure, you enter the G90G0X100. Machine will no longer be X100. But X70.721Y70.721 (should be so much
