Ultra high speed machining of aluminum alloys: Machinability aspects and attainable accuracy

This paper investigates the effect of cutting environment and tool material & configuration on tool wear, cutting forces, chip morphology and surface roughness during ultra high speed machining of A356 aluminium alloy at cutting speeds up to 7000 m/ min is. The effects of three coolant application strategies, including dry cutting, flood coolant, and Minimum Quantity of Lubricant (MQL) on the process outputs are quantified. It is concluded that …
