Two of the most dynamic machining innovations in recent years are fully examined and explained in this comprehensive review of hard milling and high speed machining. High speed machining involves the application of high feed rates and high definition cuts to rough and semi-finish parts before heat treat, and hard milling is used to machine the finish and accuracy into a part after heat treatment. The editor, Dale Mickelson (founder of Hardmilling Technologies), has combined the efforts of leading experts at Sandvik Coromant, RobbJack, Hitachi, OSG Tap and Die, and Millstar to provide a complete reference and guide to understanding and implementing these technologies. Topics covered in depth include how to select the right process for a particular job; latest developments in tool materials and geometries; cutter and toolholder selection; controlling heat generation; machine tool selection; successful programming; and machine communications. Also included are informative case studies that highlight the benefits of hard milling; mathematical formulas for calculating machining parameters such as step-over, and effective cutting diameters of ball nose and toroid tools; and speed and feed charts for a wide range of cutting operations. This indispensable reference provides the information needed to maximize machining capabilities and to understand the optimal configurations for various applications and materials.
