1.4 Motion direction naming of control axes
This system can control the rapid traverse, feeding and interpolation of four axes. The axis direction is defined
in Cartesian coordinate system, as shown below (facing to the machine tool):
Z axis: The up and down movement of the tool relative to the workpiece is Z axis motion, with the upward
movement the positive motion and the downward movement the negative motion.
X axis: The left and right movement of the tool relative to the workpiece is X axis motion, with the rightward
movement the positive motion and the leftward movement the negative motion.
Y axis: The forward and backward movement of the tool relative to the workpiece is Y axis motion, with the
forward movement the positive motion and the backward movement the negative motion.
Spindle:
Look down to the workpiece, the clockwise rotation is spindle positive rotation and the counterclockwise
rotation is negative rotation.
