undamentals
probingFeedCalc = 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
Entries in the tool table TOOL.T
r Active tool radius in mm
measureTolerance1 Maximum permissible error of measurement
Abbr. Inputs Dialog
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?
DIRECT. Cutting direction of the tool for measuring the tool during rotation Cutting direction (M3 = –)?
R_OFFS 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 L).
Input range: 0 to 0.9999 mm Breakage tolerance: radius?
