MillingRotating multiple-cutting-edge tool is moved slowlyrelative to work to generate plane or straight surface•Two forms: peripheral milling and face millingFigure 21.3 - (c) peripheral milling, and (d) face milling©2002 John Wiley & Sons, Inc.

Cutting Tool Classification1. Single-Point Tools One cutting edge Turning uses single point tools Point is usually rounded to form a nose radius2. Multiple Cutting Edge Tools More than one cutting edge Motion relative to work usually achieved byrotating Drilling and milling use rotating multiple cuttingedge tools.©2002 John Wiley & Sons, Inc.
