An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, a milling bit can generally cut in all directions, though some cannot cut axially.

Aug 31, 2006· ABSTRACT This article presents a method for obtaining the shear and ploughing specific cutting coefficients for a ballend milling cutting force model. Thus, by using the proposed calculation method, the need for introducing variable shear cutting coefficients has been identified. This fact is due to the dependency among the specific cutting coefficients and the cutting edge inclination angle ...
Abstract. A force model is presented to predict cutting forces in end milling. The helical end mill geometry model is established containing the cutting velocities and the cutting forces during the cutting process, which considers the pitch angle and the helix angle of each flute.
The tool force model provides a formula for calculating the cutting and thrust force developed during milling. The inputs to the model are the material properties (hardness, modulus), friction at the rake and flank faces of the tool, tool geometry (ball end radius), spindle speed, upfeed and cross feed, depth of cut and tilt angle of tool.

Ball nose milling of complex surfaces is common in the die/mould and aerospace industries. A significant influential factor in complex surface machining by ball nose milling for part accuracy and tool life is the cutting force. There has been little research on cutting force model for ball nose milling .
