Mill Tool Geometry 361

Mill Tool Geometry provides an overview of the possible tool angles and insert features for a multi-point milling cutter, detailing the affect each angle has on a cutting operation. The various angles, such as the axial rake and radial rake, and their positioning offer tradeoffs between cutting edge strength and cutting forces, among other important factors. Mill tool geometry must be optimized to each unique combination of workpiece material, tool material, and part feature. Improper tool geometry leads to premature tool wear or failure, poor surface finish, and slower speed and feed rates. These issues can increase manufacturing costs, create waste and scrapped parts, and slow production rates. After taking this class, users will be able to identify the various angles involved in mill tool geometry and implement the proper tool geometry for mill cutting processes.
