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.

Cycle

Soft key

7 DATUM SHIFT
For shifting contours directly within the program or
from datum tables

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
