Entries in the tool table TOOL.T

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?

Input examples for common tool types

Tool type

CUT

TT:R_OFFS

TT:L_OFFS

Drill

– (no function)

0 (no offset required
because tool tip is to be
measured)

End mill

with diameter

of < 19 mm

4 (4 teeth)

0 (no offset required
because tool diameter is
smaller than the contact
plate diameter of the TT)

0 (no additional offset
required during radius
measurement. Offset from
offsetToolAxis is used)

End mill

with diameter

of > 19 mm

4 (4 teeth)

R (offset required because
tool diameter is larger than
the contact plate diameter
of the TT)

0 (no additional offset
required during radius
measurement. Offset from
offsetToolAxis is used)

Radius cutter

4 (4 teeth)

0 (no offset required
because the south pole of
the ball is to be measured)

5 (always define the tool
radius as the offset so
that the diameter is not
measured in the radius)
