A Fuzzy Evaluation of Tool Materials in the Turning of Marine Steels

To recommend one suitable tool material for the cutting of marine steels under special conditions and requirements in emergency rescues capsized steel ships, cermet tools, cemented carbide tools coated were evaluated using a fuzzy evaluation method concerning force, temperature, surface roughness wear. Experimental results indicate that performance was diverse difficult to evaluate with single index. The presented bad severe Compared showed excellent wear resistance about 60.3% smaller flank value good quality 46.8% roughness. low temperatures 15.6% than those tools. result demonstrates best performance, followed by then are recommended cut ships.
