Tool data for automatic tool measurement
Refer to your machine manual.
The machine tool builder defines whether the R-OFFS
offset will be taken into account for a tool with CUT 0.
Your machine tool builder defines the default value for
the R-OFFS and L-OFFS columns.
Abbr. Inputs
CUT Number of teeth (99 teeth maximum)
LTOL Permissible deviation from tool length L for wear detec-
tion. If the entered value is exceeded, the control locks
the tool (status L). Input range: 0 to 0.9999 mm
RTOL Permissible deviation from tool radius R for wear detec-
tion. If the entered value is exceeded, the control locks
the tool (status L). Input range: 0 to 0.9999 mm
R2TOL Permissible deviation from tool radius R2 for wear detec-
tion. If the entered value is exceeded, the control 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.
L-OFFS Radius measurement: Tool offset between upper surface
of stylus and lower surface of tool in addition to
ToolAxis.
LBREAK Permissible deviation from tool length L for breakage
detection. If the entered value is exceeded, the control
locks the tool (status L). Input range: 0 to 3.2767 mm
RBREAK Permissible deviation from tool radius R for breakage
detection. If the entered value is exceeded, the control
locks the tool (status L). Input range: 0 to 0.9999 mm
