For example, if you use a 10mm diameter
tool with an arc
Leadin of 3mm, the calculated
Leadin arc value is 8mm. When the toolpath is
compensated on the machine, the resulting motion produces an arc move of 3mm. For other
types of
Leadin and
Leadout moves, the length and angle of the
Leadin and
Leadout line segments
automatically
adjust.
For legacy parts, you need to regenerate contour mill toolpaths for
these changes to take
effect.
