Incremental Coordinate Commands
The previous coordinates of the tool are the reference point for calculating the
coordinate value of the next position. The incremental coordinate is either positive (+)
or negative (-). The negative sign represents decrement. Facing toward the direction of
movement, if the tool is heading towards the positive (+) direction, U, W represents an
increment. If it is heading to the negative (-) direction, U, W represents decrement.
X, Z and U, W are interchangeable in the program. The commands used for absolute
and incremental coordinates are described as follows:
