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:

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:

n

Define cycles for basic behavior with a new value, such as scaling
factor 1.0.

n

Execute a miscellaneous function M02, M30, or an N999999 %...
block (depending on Machine Parameter 7300).

n

Select a new program.

n

Program miscellaneous function M142 Erasing modal program
information.

Cycle

Soft key

G53/G54 DATUM SHIFT
For shifting contours directly within the program or
from datum tables

G247 DATUM SETTING
Datum setting during program run (not TNC 410)

G28 MIRROR IMAGE
Mirroring contours

G73 ROTATION
For rotating contours in the working plane

G72 SCALING FACTOR
For increasing or reducing the size of contours

G80 WORKING PLANE
For executing machining operations in a tilted
coordinate system
for machines with tilting heads
and/or rotary tables (not TNC 410)
