- Reset during chopping
When a reset is performed during chopping, the tool immediately
moves to point R, after which chopping mode is canceled.
If an emergency stop or servo alarm occurs during chopping, mode is
canceled, and the tool stops immediately.
- Stopping chopping
The following table lists the operations and commands that can be used
to stop chopping, the positions at which chopping stops, and the
operation performed after chopping stops:
Operation/
command
Stop position Operation after
chopping stops
G80 Point R Canceled
CHPST : “0” The tool moves to the lower
dead point, then to point R.
Canceled
*CHLD : “0” Point R Restart after *CHLD
is turned “1”
Reset Point R Canceled
Emergency stop The tool stops immediately. Canceled
Servo alarm The tool stops immediately Canceled
- Single block signal
Even if the single block signal SBK is input during chopping, chopping
continues without stopping.
Limitation
- Move command during chopping
If, during chopping, an attempt is made to execute a move command on
the chopping axis, a P/S alarm (PS472) is issued.
- Canned cycle
During chopping, a canned cycle cannot be specified.
- Cutter compensation
When the chopping command (G81.1) or the cancel command (G80) is
specified, buffering (advanced read) is suppressed. So, note that when
these commands are specified in cutter compensation mode, the
method used to create a compensation vector may change.
- Three-dimensional coordinate conversion
This function does not operate in three-dimensional coordinate
conversion mode. So, cancel three-dimensional coordinate conversion
mode before starting this function.
- PMC axis
When a chopping axis is selected as a PMC axis, chopping cannot be
started.
