transformations

Overview

As an alternative to the coordinate transformation Cycle 7 DATUM
SHIFT,

you can use the TRANS DATUM plain-language function. Just as

in Cycle 7, you can use TRANS DATUM to directly program shift values or

activate a line from a selectable datum table. In addition, there is also

the TRANS DATUM RESET function, which you can easily use to reset a

datum shift.

TRANS DATUM AXIS

You can define a datum shift by entering values in the respective axes

with the TRANS DATUM AXIS function. You can define up to nine

coordinates in one block, and incremental entries are possible.

Proceed as follows for the definition:

Show the soft-key row with special functions

Select the menu for defining various plain-language

functions

Select transformations

Select datum shifting with TRANS DATUM

Enter the datum shift in the affected axes, confirming

with the ENT key each time

Example: NC block

13 TRANS DATUM AXIS X+10 Y+25 Z+42

Values entered as absolute values refer to the workpiece

datum, which is specified either by datum setting or with

a preset from the preset table.
Incremental values always refer to the datum which was

last valid (this may be a datum which has already been

shifted).
