8.9 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:
Cycle
7 DATUM SHIFT
For shifting contours directly within the
program or from datum tables
247 DATUM SETTING
Datum setting during program run
8 MIRROR IMAGE
Mirroring contours
10 ROTATION
For rotating contours in the working plane
11 SCALING FACTOR
For increasing or reducing the size of
contours
26 AXIS-SPECIFIC SCALING FACTOR
For increasing or reducing the size of
contours with scaling factors for each
axis
19 WORKING PLANE
Machining in tilted coordinate system on
machines with swivel heads and/or tilting
tables
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 M02, M30, or an END PGM block
(depending on MP7300).
Select a new program.
Program miscellaneous function M142 Erasing modal program
information.
