Starting point in 1st axis
Q225 (absolute value):
Coordinate of the starting point in the reference axis
of the working plane.
Starting point 2nd axis
Q226 (absolute value):
Coordinate of the starting point in the minor axis of
the working plane.
Spacing in 1st axis
Q237 (incremental value):
Spacing between each point on a line.
Spacing in 2nd axis
Q238 (incremental value):
Spacing between each line.
Number of columns
Q242: Number of machining
operations on a line.
Number of lines
Q243: Number of passes.
Rotational position
Q224 (absolute value): Angle by
which the entire pattern is rotated. The center of
rotation lies in the starting point.
Set-up clearance
Q200 (incremental value): Distance
between tool tip and workpiece surface.
Workpiece surface coordinate
Q203 (absolute
value): Coordinate of the workpiece surface.
2nd set-up clearance
Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
Move 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.
