8.5 Cycles for Machining Hole Patterns
U Starting point 1st axis Q225 (absolute value):
Coordinate of the starting point in the reference axis
of the working plane
U Starting point 2nd axis Q226 (absolute value):
Coordinate of the starting point in the minor axis of
the working plane
U Spacing in 1st axis Q237 (incremental value):
Spacing between the individual points on a line
U Spacing in 2nd axis Q238 (incremental value):
Spacing between the individual lines
U Number of columns Q242: Number of machining
operations on a line
U Number of lines Q243: Number of passes
U Angle of rotation Q224 (absolute value): Angle by
which the entire pattern is rotated. The center of
rotation lies in the starting point.
U Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface
U Workpiece surface coordinate Q203 (absolute
value): Coordinate of the workpiece surface
U 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
U Traversing to clearance height Q301: Definition of
how the tool is to move between machining
processes:
0: Move to set-up clearance
1: Move to 2nd set-up clearance between the
measuring points.
