10.6 NC functions for coordinate
transformations
Overview
The control provides the following TRANS functions:
Syntax Function Further
information
TRANS DATUM Shift the workpiece datum Page 383
TRANS MIRROR Mirror an axis Page 385
TRANS ROTATION Rotation about the tool axis Page 388
TRANS SCALE Scale contours and
positions
Page 389
Define the functions in the sequence in which they are listed in the
table and reset them in reverse order. The sequence of programming
will have an impact on the result.
For example, if you first shift the workpiece datum and then mirror
the contour and then reverse the sequence, the contour will be
mirrored at the original workpiece datum.
All TRANS functions reference the workpiece datum. The workpiece
datum is the origin of the input coordinate system (I-CS).

Datum shift with TRANS DATUM
Application
The TRANS DATUM function allows you to shift the workpiece datum
by either entering fixed or variable coordinates or by specifying a
table row in the datum table.
Use the TRANS DATUM RESET function to reset the datum shift.
