Programmable Work Offset: Trans, Atrans - Siemens SINUMERIK User Manual

11.2.5

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.
Note
In the X axis, the workpiece zero should be in the turning center due to the functions of diameter programming (DIAMON)
and constant cutting speed (G96). For this reason, use no offset or only a small offset (e.g. as allowance) in the X axis.
See the following effect of the programmable offset:
Programming
TRANS Z... ; programmable offset, deletes old instructions for offsetting, rotation, scaling factor, mirroring
ATRANS Z... ; programmable offset, additive to existing instructions
TRANS ; without values: clears old instructions for offset, rotation, scaling factor, mirroring
The instructions that contain TRANS or ATRANS each require a separate block.
