Programmable Work Offset: Trans, Atrans; Programmable Rotation: Rot, Arot - Siemens SINUMERIK 808D ADVANCED Programming And Operating Manual

8.2.6

Programmable work offset: TRANS, ATRANS

Functionality
The programmable work offset can be used:
● for recurring shapes/arrangements in various positions on the workpiece
● when selecting a new reference point for the dimensioning
● as a stock allowance when roughing
This results in the current workpiece coordinate system. The rewritten dimensions use this as a reference.
The offset is possible in all axes.
Programming
TRANS X... Y... Z...
ATRANS X... Y... Z...
TRANS
The instructions which contain TRANS or ATRANS each require a separate block.
See the following illustration for the example for programmable offset:
Programming example
N20 TRANS X20 Y15
N30 L10
N70 TRANS
Subroutine call - see Section "Subroutine technique (Page 110)".
8.2.7

Programmable rotation: ROT, AROT

Functionality
The rotation is performed in the current plane G17 or G18 or G19 using the value of RPL=... specified in degrees.
Programming
ROT RPL=...
AROT RPL=...
ROT
