cutting cycles ("Turning" → "Plunge–cutting").
> 0 = Dwell time in seconds
< 0 = Dwell time in spindle revolutions

Finishing feed in percent
Min. input limit: 1
Protection level: 3/4
This MD is used to stipulate a feed rate for the finishing process when complete machining
"Roughing and finishing" is selected; this feed rate is a percentage of the value entered for
parameter F (feed rate).
$MM_CTM_MAX_T OOL_WEAR
Upper input limit for tool wear
Min. input limit: 0
Protection level: 3/4
With this MD you define the upper absolute limit for tool wear (length, radius). This means
that the total value must not exceed the upper absolute limit when entering the wear value
in the tool wear list.
The incremental upper limit is defined in MD 9450 $MM_WRITE_TOA_FINE_LIMIT .
