G90 G91 absolute and relative programming
Function:
Tool motion instructions include absolute value instruction and increment value instruction. In absolute value
instruction mode, the coordinate value of the motion end in current coordinate system is specified; in
increment value instruction, the distance of every coordinate axis relative to the start point motion is specified.
Format:
G90 X_ Y_ Z_ α_;
G91 X_ Y_ Z_ α_;
G90……… absolute value instruction
G91……… increment value instruction
α……… additional axis
Details:
In absolute value instruction mode, the tool motion is unrelated to current position, and moves according to the
position of specified workpiece coordinate system;
In increment value instruction, the current position is the start point;
