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 with a
diameter of 10 mm, for
example
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)
