12. Tool Offset Functions
(2) Offset No.
(a) The offset amount differs according to the compensation type.
Type 1
G43 Hh
When the above is commanded, the offset
amount lh
be applied commonly regardless of the tool
length offset amount, tool diameter offset
amount, shape offset amount or wear offset
amount.
Type 2
G43 Hh
When the above is commanded, the offset
amount lh
be as follows.
lh : Shape offset (Note) + wear offset amount
1
(b) The valid range of the offset No. will differ according to the specifications (No. of offset
sets).
(c) If the commanded offset No. exceeds the specification range, the program error "P170"
will occur.
(d) Tool length cancel will be applied when H0 is designated.
(e) The offset No. commanded in the same block as G43 or G44 will be valid for the following
modals.
(Example 3)
(f) If G43 is commanded in the G43 modal, an offset of the difference between the offset No.
data will be executed.
(Example 4)
The same applies for the G44 command in the G44 modal.
