Aerospace, structural parts
The pocket contour can be programmed on
ISD based on
the basis of the pocket floor, in which case the
pocket floor,
ISD is 0.
workpiece surface
Alternatively, the contour can be programmed
in relation to the workpiece surface and in this
case the insertion depth ISD is 41.231 (length
of pocket wall). The radii will need to be
adjusted.
The adjustment can be calculated using
Pythagoras' theorem.

,
ISD = 40 + 10 = 41 231
