Analytical Chip Load Prediction for Rough End Mills

Rough end mills with serrated cutting edges are effectively used for suppressing chatter vibrations encounter during milling operations. In this study, serrated cutting edges are analytically defined and geometrically modelled by a NURBS curve. The chip load on the serrated cutting edges is computed by newly proposed recursive algorithm. It is shown that the proposed model can be used in estimating the chip load of rough end mills during operation. Validity and accuracy of the recursive algorithm is geometrically verified with ASIC 3D solid modeller. The developed algorithm can be effectively implemented for static and dynamic simulation of cutting process.
