Design for Milling
                                    In the case of milling inserts, the rake face shape
                                    is considered mainly from the point of view of chip
                                    forming only - milling is a process of interrupted cutting
                                    and therefore chip breaking creates no difficulties.
                                    The rake face of the turning insert is also intended
                                    mainly for chip formation, though it should enable chip
                                    breaking. In the context of geometry, the rake face of
                                    every indexable insert is a combination of concave and
                                    convex areas.


                                    Effect of 3D Modelling
                                    Three-dimensional chip formation modelling represents
                                    a new powerful design tool for the cutting tool industry.
                                    Further development, based on the finite element
                                    method (FEM), raised cutting action modelling systems
                                    to a whole new level.
                                    Today, cutting tool designers utilize advanced software
                                    to simulate chip formation processes with a sufficient
                                    approximation to reality.



                                        Even though the software

                                    still cannot replace machining
                                    tests, it can contribute greatly

                                     to the effective design of the

                                      indexable inserts and, most
                                           of all, their rake faces
