Cycle Parameters - HEIDENHAIN TNC 620 User Manual

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
machining 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 lines
Angle of rotation 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. Input range
0 to 99999.9999
Coordinate of workpiece surface Q203 (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
2nd set-up clearance Q204 (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Traversing to clearance height Q301: 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
