Detailed description
2.1 Circumferential milling
Figure 2-1
Insertion depth (ISD)
Program command ISD (insertion depth) is used to program the tool insertion depth for
circumferential milling operations. This makes it possible to change the position of the
machining point on the outer surface of the tool.
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. ISD is evaluated
only when 3D TRC is active.
