The three geometry axis identifiers are used as index <n>. Thus, the number of active direction
offsets is determined by the geometry axes that are active at the same time.
All offsets can be active at the same time.
The online tool length offset function can be used for:
● Orientation transformation TRAORI
● Orientable toolholder TCARR
Note
Online tool length offset is an option, which must be enabled in advance. This function is
only practical in conjunction with an active orientation transformation or an active orientable
toolholder.
Syntax
TRAORI
TOFFON(<compensation direction>[,<offset value>])
WHEN TRUE DO $AA_TOFF[<compensation direction>] ; In synchronized actions.
...
TOFFOF(<compensation direction>)
Meaning
TOFFON: Activate online tool length offset
<compensation
direction>:
Tool direction (X, Y, Z), in which the online tool length
offset should be active.
<offset value>: When activating, an offset value can be specified for
the relevant direction of compensation and this is im‐
mediately recovered.
TOFFOF: Reset online tool length offset
The compensation values in the specified compensation direction are reset and a pre-
processing stop is initiated.
Examples
