ISCAR'S FACE & SHOULDERS MILLS

The world of metalworking is undergoing major changes. Complex machining processes are unimaginable without the utilization of face milling operations. Face milling processes facilitate the preparation of datum surfaces by producing planes and flats and enable improving precision and surface quality parameters. Moreover, the production of many rotating parts is incomplete without face milling. Face milling is the very operation that cannot be undermined.

In face milling, the axis of a cutter is normal to the machined surface. A large majority of face mills or surface milling cutters are common indexable tools in shell mill configuration. They feature various tool cutting edge angles (entering angles) such as 45°, 60°, 65°, 75°, 90°. Face mills intended specifically for productive rough machining by use of high feed milling (HFM) methods have a significantly smaller cutting-edge angle, typically 10°-17°. In some cases, shell mills that mount round inserts enable extremely strong cutting edges. The cutting-edge angle has an impact on the decomposition of the cutting force, which acts on the plane of the cutter axis, on radial and axial components referred to as radial, and axial cutting forces. With all else being equal, this angle defines the maximum depth of cut. The cutting-edge angle largely determines the application field of a face mill making 45° face mills most versatile. Such mills have an important advantage that stipulates a firstchoice selection of 45° cutters in face milling, specifically when machining open plane surfaces. These cutters assure a good balance of radial and axial cutting forces, a high-quality machined surface, and favorable cutting conditions when a tool enters or exits the material being machined. The most common face mill types are 45° cutters.
