Dynamic Simulation and Cutting Conditions Optimization of Tee Slot Milling Based on CutPro Software

Abstract

. Based on the dynamic simulation module of CutPro, the dynamic cutting forces and chatter limits for tee slot milling were predicated by setting the geometry of a tee slotting cutter. The chatter stability lobes under a given axial depth of cut are obtained by further programming, which is essential for chatter-free tee slot milling. A methodology of cutting conditions optimization for tee slot milling is presented, in which the minimal cutting time is used as the target function and the stability limits are introduced into the constraint conditions to reflect the vibration characteristics of milling operation. This optimization method has been validated by experimental tests.
