The recessing cycles G861 to G868 and re-
cess-turning cycles G81x and G82x auto-
matically take the “correct“ wear compensa-
tion into account.

ool-tip and milling cut

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.
