7.7 7.7 Online tool length compensation (TOFFON, TOFFOF)
Function
Use the system variable $AA_TOFF[ ] to overlay the effective tool lengths in accordance with
the three tool directions three-dimensionally in real time.
The three geometry axis identifiers are used as the index. This defines the number of active
directions of compensation by the geometry axes 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
Machine manufacturer
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.
Programming
N.. TRAORI
N.. TOFFON(X,25)
N.. WHEN TRUE DO $AA_TOFF[tool direction] in synchronized actions
For more information about programming online tool length offset in motion-synchronous
actions, see "Actions in synchronized actions".
Parameters
TOFFON
Tool Offset ON (activate online tool length offset)
When activating, an offset value can be specified for the relevant
direction of compensation and this is immediately recovered.
TOFFOF
Tool Offset ON (reset online tool length offset)
The relevant offset values are reset and a preprocessing stop is
initiated.
X, Y, Z Direction of compensation for the offset value indicated for TOFFON
