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 < 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 > 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)
