With additional linear axis and groove wall offset (transformation type 514)
On a machine with a second linear axis, this transformation variant makes use of redundancy in order to perform improved
tool compensation. The following conditions then
apply to the second linear axis:
● A smaller working area
● The second linear axis should not be used for traversing the part program.
Certain machine data settings are assumed for the part program and the assignment of the corresponding axes in the BCS
or MCS.
For more information, see the SINUMERIK 808D/SINUMERIK 808D ADVANCED Function Manual.
Offset contour normal OFFN (transformation type 513)
To mill grooves with TRACYL, the following is programmed:
● Groove center line in the part program
● Half the groove width programmed using OFFN.
To avoid damage to the groove side OFFN acts only when the tool radius compensation is active. Furthermore, OFFN
should also be >= the tool radius to avoid damage occurring to the opposite side of the groove.
