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 separately. 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 machine parameter clearMode).
