If you know by what processing the tool figure and setting method are
defined when tool data were input to the Symbolic FAPT system, you will
be able to program these tool more securely.
Data employed by the system for checking the cutting direction, cutting
edge angle, and other tool figures are angles indicating the tool nose
directions in the NC data coordinate system.
In the NC data coordinate system, the counterclockwise angle as viewed
from the plus (+) Z direction shows a positive (+) angle, while the
clockwise angle shows a negative () angle.
For example, 135° and –225° or 180°
and –180° have the same meanings,
respectively.
Two cutting edges are present normally. They are called major cutting
edge and minor cutting edge. These cutting edge directions are called
major cutting edge direction angle and minor cutting edge direction angle.
In the above figure, the major cutting edge direction angle is 240° or
–120° , while the minor cutting edge direction angle is –165° or 195°.
Now, the process or determining the tool figure and setting methods in the
Symbolic FAPT will be described in regular sequence, referring to the
above description.
