8.12 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 a miscellaneous function M2, M30, or an END PGM block
(depending on MP7300).
Select a new program.
Program miscellaneous function M142 Erasing modal program
information.
