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 Dialog
CUT
Number of teeth (99 teeth maximum)
Number of teeth?
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
Wear tolerance: length?
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
Wear tolerance: radius?
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
Wear tolerance: Radius 2?
DIRECT
Cutting direction of the tool for measuring the tool during
rotation
Cutting direction? M4=ENT/
M3=NOENT
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 control
locks the tool (status
L
). Input range: 0 to 3.2767 mm
Breakage tolerance: length?
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
Breakage tolerance: radius?
