Abstract

The objectives of this study were to investigate the possibility of optimizing the cutting performance for dies materials machining process from hard steel using different coated Cobalt-cemented tungsten carbide (WC–Co) tool inserts (substrates) for finish turning carbon steel (AISI D2). In addition, comparison between uncoated and coated inserts was performed depending on machining speed, feed, and cutting depth without cooling fluids. Chips types and work piece surface roughness were also studied. As a result we were able to increase cutting tool life which will influence the machining process cost. 

Keywords: Cutting tools, Dies forming, hardest conditions, Manufacturing.
