Cycle parameters
 Starting point in 1st axis
Q225 (absolute):
Coordinate of the starting point in the reference axis
of the working plane.
 Starting point 2nd axis Q226 (absolute): Coordinate
of the starting point in the minor axis of the working
plane.
 Spacing in 1st axis
Q237 (incremental): Spacing
between each point on a line.
 Spacing in 2nd axis
Q238 (incremental): 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): Angle by
which the entire pattern is rotated. The center of
rotation lies in the starting point.
 Set-up clearance
Q200 (incremental): Distance
between tool tip and workpiece surface; alternatively
PREDEF
.
 Workpiece surface coordinate Q203 (absolute):
Coordinate of the workpiece surface.
 2nd set-up clearance
Q204 (incremental): Coordinate
in the spindle axis at which no collision between tool
and workpiece (fixtures) can occur; alternatively
PREDEF
.
 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.
