8.11.3 Workpiece count monitoring
The workpiece count of the active cutting edge of the active tool is monitored.
The workpiece count monitoring records all tool cutting edges used to produce a workpiece.
If the count is changed due to new values specified, the monitoring data are adapted to all
tool cutting edges that became active since the last workpiece count.
Updating the workpiece count by operator input or SETPIECE( )
The workpiece count can be updated by an operator input (HMI) or in the NC program
through the SETPIECE( ) language command.
With the SETPIECE function, the user can update the workpiece count monitoring data of
the tools involved in the machining process.
If SETPIECE(n) is programmed, the internal setpiece memory is searched. If this “memory”
is set for one cutting edge of a tool, the part quantity (remaining part quantity – $TC_MOP4)
of the respective cutting edge is decremented by the specified value and the respective
“memory” (setpiece memory) is deleted.
SETPIECE(n )
n : = 0... 32000 Number of workpieces that have been produced since the last execution of
the
SETPIECE function. The counter status for the remaining part quantity
($TC_MOP4[t,d] )
is reduced by this value.
Programming example
N10 G0 X100
N20 ...
N30 T1
N40 M6
N50 D1
... ; Machining using T1, D1
N60 SETPIECE(1) ; $TC_MOP4[1,1 ] (T1,D1) is decremented by 1
N90 T2
N100 M6
N110 D2
... ; Machining using T2, D2
N200 SETPIECE(1) ; $TC_MOP4[2,2 ] (T2,D2) is decremented by 1
...
N300 M2
Notes:
S The SETPIECE( ) command is not active during the block search.
S Direct writing of $TC_MOP4[t,d] is recommended only in simple cases. A subsequent
block with the STOPRE command is required.
Setpoint refreshing
Setpoint refreshing, i.e. setting the remaining workpiece counters ($TC_MOP4[t,d]) to the
workpiece count setpoint ($TC_MOP13[t,d]) is typically performed via operator input (HMI).
It can, however, also be performed through the RESETMON (state, t, d, ,mon) function as
already described for the tool life monitoring.
