WEAR PERFORMANCE OF FLAT END-MILL CUTTER DURING MACHINING OF COPPER BASED METAL

This paper presents some research into the wear and damage of the flat end-mill cutting tools under machining with copper based metal. A series of cutting tests have been carried at cutting time 35, 70, 105, and 140 minutes. The cutting speed, depth of cut and feed rate were kept constant at 2750 rpm, 0.05 mm and 280 mm/min, respectively. The experimental results showed that significant flank wear was the predominant failure mode which concentrated at the edges of the cutting tools. The flank wear of flat end-mill cutting tool increased with cutting speed and time, presenting a considerably various tool wear behaviour.
