7 This process (6) is repeated until all machining operations in the
second line have been executed.
8 The tool then moves to the starting point of the next line.
9 All subsequent lines are processed in a reciprocating movement.
ú Starting point 1st axis Q225 (absolute value):
Coordinate of the starting point in the main axis of the
working plane
ú Starting point 2nd axis Q226 (absolute value):
Coordinate of the starting point in the secondary axis
of the working plane
ú Spacing in 1st axis Q237 (incremental value): Spacing
between the individual points on a line
ú Spacing in 2nd axis Q238 (incremental): Spacing
between the individual lines
ú Number of columns Q242: Number of machining
operations on a line
ú Number of lines Q243: Number of passes
ú Angle of rotation Q224 (absolute value): Angle by
which the entire pattern is rotated. The center of
rotation lies in the starting point.
ú Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.
ú Workpiece surface coordinate Q203 (absolute value):
Coordinate of the workpiece surface
ú 2nd set-up clearance Q204 (incremental value):
Coordinate in the tool axis at which no collision
between tool and workpiece (clamping devices) can
occur.
