High Speed Machining

High speed machining typically refers to making light milling passes at high spindle speed and feed rate to achieve a high metal removal rate. This practice can be effective for machining intricate core and cavity geometries in mold machining, and for quickly machining large, complex aircraft structural components out of solid blocks of aluminum.
