The recessing cycles G861 to G868 and re-
cess-turning cycles G81x and G82x auto-
matically take the correct wear compensa-
tion into account.
Tool-tip and milling cutter
radius compensation
Tool-tip and milling cutter radius compensation (TRC,
MCRC) G40, G41, G42
G40: Switch off TRC/MCRC
TRC/MCRC remains in effect until a block with G40 is reached.
The block containing G40, or the block after G40 muct contain a linear
path of traverse (G14 is not permissible).
G41/G42: Switch on TRC/MCRC
A linear path of traverse (G0/G1) must be programmed in or after the
block containing G41/G42.
TRC/MCRC is taken into account from the next path of traverse.
G41: TRC/MCRC with direction of traverse to the left of the contour
inside machining (with direction of traverse in Z)
G42: TRC/MCRC with direction of traverse to the right of the contour
outside machining (with direction of traverse in Z)
(Changing the) cutter compensation G148
With O you can define which wear compensation values are to be
taken into account.
DX and DZ become effective after program start and after a T com-
mand.
Parameters
O: Selection default: 0
O=0: DX, DZ active
O=1: DS, DZ active
O=2: DX, DS active
Some recessing and roughing cycles as well
as the milling cycles already include the
TRC/MCRC calls. You must therefore ensure
that TRC/MCRC is disabled before you call
these cycles. The commands G40, G41, G42
must not be used within the cycles.
