Fundamentals

10.1 Fundamentals

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:
Soft key Cycle
7 DATUM
For shifting contours directly
within the program or from
datum tables
247 DATUM SETTING
Datum setting during program
run
8 MIRRORING
Mirroring contours
10 ROTATION
Rotating contours in the
working plane
11 SCALING FACTOR
Increasing or reducing the size
of contours
26 AXIS-SPECIFIC SCALING
Increasing or reducing the size
of contours with axis-specific
scaling
19 WORKING PLANE
Machining in tilted coordinate
system on machines with
swivel heads and/or rotary
tables

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).
