137 HEIDENHAIN TNC 310
8.6 Coordinate Transformation
Cycles
Once a contour has been programmed, you can position it on the
workpiece at various locations and in different sizes through the
use of coordinate transformations. The TNC provides the following
coordinate transformation cycles:
Cycle Soft key
7 DATUM SHIFT
For shifting contours directly within the program
8 MIRROR IMAGE
For mirroring contours
10 ROTATION
For rotating contours in the working plane
11 SCALING FACTOR
For increasing or reducing the size of contours
Effect of coordinate transformations
A coordinate transformation becomes effective as soon as it is
defined — it is not called. It remains in effect until it is changed or
canceled.
To cancel coordinate transformations:
■ Define cycles for basic behavior with a new value, such as scaling
factor 1.0
■ Execute a miscellaneous function M02, M30, or an END PGM
block (depending on machine parameter 7300)
■ Select a new program
