7.11 Cutting data modification for tools that can be rotated (CUTMOD)
<value>
518
The following values can be assigned to the CUTMOD command:
0 The function is deactivated.
The values supplied from system variables $P_AD... are the same as
the corresponding tool parameters.
> 0 The function is activated if a toolholder that can be orientated with the
specified number is active, i.e. the activation is linked to a specific
toolholder that can be orientated.
The values supplied from system variables $P_AD... may be modified
with respect to the corresponding tool parameters depending on the
active rotation.
The deactivation of the designated toolholder that can be orientated
temporarily deactivates the function; the activation of another
toolholder that can be orientated permanently deactivates it. This is
the reason that in the first case, the function is re-activated when
again selecting the same toolholder that can be orientated; in the
second case, a new selection is required - even if at a subsequent
time, the toolholder that can be orientated is re-activated with the
specified number.
The function is not influenced by a reset.
-1 The function is always activated if a toolholder that can be orientated
is active.
When changing the toolholder or when de-selecting it and a
subsequent new selection, CUTMOD does not have to be set again.
-2 The function is always activated if a toolholder that can be orientated
is active whose number is the same as the currently active toolholder
that can be orientated.
If a toolholder that can be orientated is not active, then this has the
same significance as CUTMOD=0. If a toolholder that can be orientated
is active, then this has the same significance as when directly
specifying the actual toolholder number.
< -2 Values less than 2 are ignored, i.e. this case is treated as if CUTMOD
was not programmed.
Note:
This value range should not be used as it is reserved for possible
subsequent expansions.
