12. Tool Offset Functions
Type 1
One offset amount corresponds to one offset No. as shown on the right. Thus, these can be
used commonly regardless of the tool length offset amount, tool diameter offset amount,
shape offset amount and wear offset amount.

Offset No.
Type 2
The shape offset amount related to the tool length, wear offset amount, shape offset related to
the tool diameter and the wear offset amount can be set independently for one offset No. as
shown below.
The tool length offset amount is set with H, and the tool diameter offset amount with D.
(H1) = b1 + c1, (D1) = d1 + e1
(H2) = b2 + c2, (D2) = d2 + e2

CAUTION
If the tool offset amount is changed during automatic operation (including during single block
stop), it will be validated from the next block or blocks onwards.
