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 workpiece count is changed by an operator input, the monitoring data of all the cutting
edges that have become active since the last workpiece count are adjusted.
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( ) function.
With the SETPIECE function, the user can refresh the workpiece count monitoring data of
the tools that were involved in the machining process. All tools with the D numbers that have
become active since the last time SETPIECE was activated are included in the update. If a
tool is active at the time SETPIECE is called, this is counted as well.
As soon as a block with path axis movements is executed after SETPIECE( ) this tool is also
considered for the subsequent SETPIECE call.
SETPIECE(x )
x = 1... 32000
x = 0

The number of workpieces that have been produced since the last
execution of the SETPIECE function. The counter status for the remaining
part quantity ($TC_MOP4[t,d] ) is reduced by this value.
Deleting all counts for the remaining workpiece count ($TC_MOP4[t,d] )
for the tools/D number that have been involved in machining since that
point of time. Alternatively, deletion via operator input (HMI) is
recommended.
; $TC_MOP4[1,2 ] (T1,D2) is decremented by 2
; $TC_MOP4[2,1 ] (T2,D1) and $TC_MOP4[1,2 ] are
; decremented by 4
; $TC_MOP4[3,2 ] (T3,D2) and $TC_MOP4[2,1 ] (T2,D1) and
; $TC_MOP4[1,2 ] decremented by 6
; Deletes all above $TC_MOP4[t,d ]
