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.
