HIGH SPEED MACHINING OF BRASS ROD ALLOYS

Abstract

Brass is known for excellent machinability, but its ultimate productivity potential with high speed machining requires further study. An extensive testing program was conducted in laboratory and production settings on representative brass rod alloys using modern machine tools. Machinability data collected for turning, drilling and milling offers new insights on the effects of increasing speed, feed rate and depth of cut on tool life, efficiency, surface integrity and chip formation. The results show that advancements in machine tool technology, coupled with the underutilized high speed machining capabilities of brass, offer new opportunities for manufacturers to become more productive and profitable.
