Tool length offset
The tool tip is the reference point for length offset (intersection longitudinal axis/surface).
3D tool offset, tool change
A new tool with modified dimensions (R, r, a) or a different shaft may only be specified with
the programming of
This rule does not apply to any other tool data, e.g., tool lengths, so that tools can be loaded
without reprogramming
9.5.4 3D tool offset Offset on the path, path curvature, insertion depth (CUT3DC, ISD)
Function
Offset on the path
With respect to face milling, it is advisable to examine what happens when the contact point
"jumps" on the tool surface as shown in the example on the right where a convex surface is
being machined with a vertically positioned tool. The application shown in the example
should be regarded as a borderline case.
