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
r Active tool radius in mm
measureTolerance1 Maximum permissible error of measurement
Entries in the tool table TOOL.T
Abbr. Inputs
Number of teeth (20 teeth maximum)
CUT
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
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
DIRECT. Cutting direction of the tool for measuring the tool during rotation
R_OFFS Tool length measurement: Tool offset between stylus center and
tool center. Default setting: No value entered (offset = tool radius)
L_OFFS Tool radius measurement: tool offset in addition to offsetToolAxis
between upper surface of stylus and lower surface of tool. Default:
0
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
Permissible deviation from tool radius R for breakage detection. If
RBREAK
the entered value is exceeded, the TNC locks the tool (status L).
Input range: 0 to 0.9999 mm
