Can milling compete with grinding for rapid stock removal?

Many times in making parts for aerospace engines with high temperature alloys like IN-718, Rene-95 and Waspaloy it is necessary to remove large amounts of material. Traditionally companies use, milling, turning or broaching to remove most of the material and then finish-grind to size. The engineers at Norton/Saint-Gobain's Higgins Grinding Technology Center have determined that for these materials grinding can, in many instances, remove the material more quickly and economically than turning or milling.

Effective flute grinding

Whether you are grinding HSS or Tungsten Carbide, the flute grinding process is the most difficult feature to grind in round tool manufacturing. Though there are many reasons why, the main reason is that this operation is where most material is being removed from the tool, introducing the most heat and spindle load. There are several techniques that can be used to allow the grinding wheel to perform this operation more effectively.
