Chaining rule

The geometry tool length compensations, wear and base dimension can be chained for both
the left and the right tool nose radius compensation, i.e. if the tool length compensations are
changed for the left cutting edge, then the values are also automatically entered for the right
cutting edge and vice versa.

6.6 Tool offset call (D)
Cutting edges 1 to 8 (with active tool management 12) of a tool can be assigned different tool
offset data blocks (e.g. different offset values for the left and right cutting edge of a grooving
tool).
Activation of the offset data (including the data for the tool length offset) of a special cutting
edge is performed by calling the D number. When D0 is programmed, offsets for the tool have
no effect.
A tool radius compensation must also be activated via G41/G42.
Note
Tool length offsets take immediate effect when the D number is programmed. If no D number
is programmed, the default setting defined via the machine data is active for a tool change
(→ see machine manufacturer's specifications).
