Thermal analysis of chip formation using FEM and a hybrid explicit-implicit approach

Modeling machining operations has been a challenge since the 1900s. It has been by empirical, science-based, and computer-based modeling, which started with FEM by the 1970s. For success material, rupture, friction, and convection have to be correctly modeled. Computation time has always been one of...

Summary:Modeling machining operations has been a challenge since the 1900s. It has been by empirical, science-based, and computer-based modeling, which started with FEM by the 1970s. For success material, rupture, friction, and convection have to be correctly modeled. Computation time has always been one of the main limitations for accurately describing heat propagation on machining. The present work proposes and tests a hybrid model using an explicit algorithm for the chip formation and an implicit one for heat propagation. Heat flux on workpiece and tool were obtained by the explicit and used as input to the implicit. Simulated results were in good agreement with experimental end milling for very short periods of computer time.
