Tool table: Tool data required 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.
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. Default setting: No value entered
(offset = tool radius)
L-OFFS
Tool radius measurement: tool offset in addition to
offsetToolAxis
lower surface of tool. Default: 0
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
