Description
Command to switch-in the function "cutting data modification for tools that can
CUTMOD
be rotated"
The following values can be assigned to the CUTMOD command:
<value>
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.
Note
SD42984 $SC_CUTDIRMOD
The function can be activated using the CUTMOD command replaces the function that can be
activated using the setting data SD42984 $SC_CUTDIRMOD. However, this function
remains available unchanged. However, as it doesn't make sense to use both functions in
parallel, it can only be activated if CUTMOD is equal to zero.
