6.8 Compensation Values
(Changing the) cutter compensation G148
MANUALplus manages three wear compensation values for
recessing tools (DX, DZ, and DS). The parameter "O" allows you to
define which wear compensation values are to be taken into account.
DX, DZ become effective after program start and after a T command
(G148 O0). The compensation values defined with G148 remain in
effect until the next T command or the end of the program.
Before you can use G148, you must assign the compensation values
DX, DZ and DS to the cutting edges of the recessing tool tip with the
"tool orientation" function (see “Recessing and recess-turning tools”
on page 421).

The recessing cycles G861 to G868 automatically take the
"correct" wear compensation into account.
