Mechanics of cutting model for simulated oblique rotary tool cutting processes

Abstract

Rotary tool cutting processes are described and simulated as 'orthogonal' and 'oblique'. A modified thin shear zone mechanics of cutting model for driven and self-propelled 'oblique' rotary cutting tool processes are developed and experimentally verified, qualitatively and quantitatively over a wide range of process variables. The cutting model has been represented as an 'equivalent' classical oblique cutting process, accounting for all the cutting energy, together with a chip transportation process due to the lateral tool movement along the cutting edge, which involves no additional energy. From a predictive point of view, the forces, power and absolute chip flow direction in 'oblique' rota..
