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?
R2TOL
Permissible deviation from tool radius R2 for wear detection. If 
the entered value is exceeded, the TNC locks the tool (status L). 
Input range: 0 to 0.9999 mm
