tool age exceeds this value, the TNC changes the tool during the
next TOOL CALL (see also CUR.TIME). Maximum tool age for TOOL CALL?
CUR.TIME Time in minutes the tool has been in use: The TNC automatically

CUT Number of teeth (20 teeth maximum) Number of teeth ?
LTOL Permissible deviation from tool length L for wear detection. If the
entered value is exceeded, the TNC locks the tool (status L). Input
range: 0 to 0.9999 mm Wear tolerance: length ?
RTOL Permissible deviation from tool radius R for wear detection. If the
entered value is exceeded, the TNC locks the tool (status L). Input
range: 0 to 0.9999 mm Wear tolerance: radius ?

TT:R-OFFS For tool length measurement: tool offset between stylus center
and tool center. Preset value: Tool radius R (NO ENT means R). Tool offset: radius ?
TT:L-OFFS Tool radius measurement: tool offset in addition to MP6530
between upper surface of stylus and lower surface of tool. Preset
value: 0 Tool offset: length ?
LBREAK Permissible deviation from tool length L for breakage detection. If
the entered value is exceeded, the TNC locks the tool (status L).
Input range: 0 to 0.9999 mm Breakage tolerance: length ?
RBREAK Permissible deviation from tool radius R for breakage detection. If
the entered value is exceeded, the TNC locks the tool (status L).
