PROGRAMMING
G40 Cancel Cutter Radius
Compensation
The cutter radius compensation will be cancelled by
G40.
Cancellation is only permitted with a linear traversing
command (G00, G01).
G00 or G01 can be programmed in the same block or
as the first traversing movement after cancellation.
G40 is programmed frequently in the block with
return to the tool change position.
G41 Cutter Radius
Compensation Left
If the programmed tool path (viewed in the direction
of machining) is on the left of the material to be
machined, the cutter radius is to be selected with
G41.
Note
• No direct change between G41 and G42 - cancel
with G40 previously.
• Cutter radius R and cutter position (tool type) must
be defined.
• Selection is only permitted in conjunction with G00
or G01.
• Change of the tool correction is not possible while
cutter radius compensation.
G42 Cutter Radius
Compensation Right
If the programmed tool path (viewed in the direction
of machining) is on the right of the material to be
machined, the cutter radius is to be selected with
G42.
Note see G41!
