= ConstantFeed:
The feed rate for probing remains constant, the error of measurement,
however, rises linearly with the increase in tool radius:
Measuring tolerance = r • measureTolerance1/ 5 mm, where

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 I). Input
range: 0 to 0.9999 mm
Wear tolerance: radius?
DIRECT.
Cutting direction of the tool for measuring the tool during rotation
Cutting direction (M3 = –)?
R_OFFS
For tool length measurement: Tool offset between stylus center
and tool center. Default setting: No value entered (offset = tool
radius)
Tool offset: radius?
L_OFFS
Tool radius measurement: tool offset in addition to
offsetToolAxis
between upper surface of stylus and lower
surface of tool. Default: 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 I).
Input range: 0 to 0.9999 mm
Breakage tolerance: radius?
