Q226 (absolute value):
Coordinate of the starting point in the minor axis of
the working plane.
8
Spacing in 1st axis
Q237 (incremental value):
Spacing between each point on a line.

Q200 (incremental value): Distance
between tool tip and workpiece surface.
8
Workpiece surface coordinate
Q203 (absolute
value): Coordinate of the workpiece surface.
8
2nd set-up clearance
Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
8
Moving to clearance height
Q301: Definition of how
the tool is to move between machining processes.
0: Move to the set-up clearance between operations.
1: Move to the 2nd set-up clearance between
machining operations.
