Analytical modeling of drilling and ball end milling

Abstract

In the present work, analytical modeling is used to analyze both the drilling and ball end milling operations. The cutting edges of the twist drill lip and the ball end mill are divided into oblique cutting elements that have geometries and cutting conditions that vary with the location of the element on the cutting edge. The analysis is performed for each element using flow stress data and thermal properties of the workpiece material, tool geometry and cutting conditions. Predicted temperatures on the flank side of the twist drill lip and predicted ball end milling force results are compared with published experimental data.
