Multiple-axis machining | Three-dimensional tool compensation (option9)
Suppressing error messages with positive tool oversize:
M107
Standard behavior
With positive tool compensation, programmed contours may be
damaged. For NCprograms with surface-normal blocks, the control
checks whether critical oversizes result from tool compensations,
and issues an error message if this is the case.
With Peripheral Milling the control triggers an error message in the
following cases:

With Face Milling the control triggers an error message in the
following case:

Behavior with M107
With M107 the control suppresses the error message.
Effect
M107 takes effect at the end of block.
You can reset M107 with M108.
With the M108 function you can also have the radius of
a replacement tool be checked even if three-dimensional
tool compensation is not active.
