2. CAUTIONS FOR USING
VARIOUS FUNCTIONS AND
PRECAUTIONS OF Symbolic FAPT
For the cutting direction vector (A) as viewed from the tool tip, and the
cutting edge angle vector of major cutting edge (B) and the cutting edge
angle vector of minor cutting edge (C) as viewed from the tool tip by
taking the cutting edge protective angle (standard value: 3°) into
D an error is produced, if the rotating direction from A to B does not meet
the rotating direction from B to C, and also
D an error is produced if A meets B.
Example when the cutting direction is °;
When cutting is made at the minor cutting edge, consider the above
explanation by exchanging vectors B and C.
