Tool offsets

8.5 Activate 3D tool offsets (CUT3DC..., CUT3DF...)

Insertion depth (ISD)

ISD is only evaluated when 3D tool radius compensation is active.

Program command ISD (insertion depth) is used to program the tool insertion depth for

peripheral milling operations. This makes it possible to change the position of the machining

point on the outer surface of the tool.

3D tool compensation circumference milling

Point FH is obtained by projecting the programmed machining point onto the tool axis.

Activate 3D tool offset for circumferential milling, e.g.,

for pocket milling with oblique side walls.

ISD defines the distance between cutter tip FS and cutter

construction point FH.
