Cycle parameters
Q225 Starting point in 1st axis? (absolute):
Coordinate of the starting point in the major axis of
the working plane
Q226 Starting point in 2nd axis? (absolute):
Coordinate of the starting point in the minor axis of
the working plane
Q237 Spacing in 1st axis? (incremental): Spacing
between the individual points on a line
Q238 Spacing in 2nd axis? (incremental): Spacing
between the individual lines
Q242 Number of columns?: Number of machining
operations on a line
Q243 Number of lines?: Number of lines
Q224 Angle of rotation? (absolute): Angle by which
the entire pattern is rotated. The center of rotation
lies in the starting point.
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface Input range
0 to 99999.9999
Q203 Workpiece surface coordinate? (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Q301 Move to clearance height (0/1)?: Definition
of how the touch probe is to move between
machining operations:
0: Move at set-up clearance between machining
operations
1: Move at 2nd set-up clearance between machining
operations
