Programming
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
CUT3DC
Parameters
CUT3DC Activate 3D tool offset for circumferential milling, e.g.,
for pocket milling with oblique side walls.
ISD ISD defines the distance between cutter tip FS and cutter
construction point FH.
Point FH is obtained by projecting the programmed machining point onto the tool axis.
