Dynamical Simulation of Chip Generaion and Formation in Metal Cutting // Tomsk State Pedagogical University Bulletin. 2004. Issue 6 (43). P. 76-81

The two-dimensional finite difference method is applied to model the metal cutting process where the contact interaction between the cutter and work piece is defined. Lagrange description of motion is used which includes the generation of new surfaces as the work piece fractures and chip separates. A cutting path is thus developed and simulated by splitting the nodes of the finite element grid. Special attention is given to the loading process of the cutting tool during the cut-in stage. Chip formation at different times are calculated and presented
