8.7 Coordinate Transformation
Cycles
Overview
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:
Effect of coordinate transformations
Beginning of effect: 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 the miscellaneous function M02 or M30, or an END PGM
block (depending on the clearMode machine parameter)
„ Select a new program
