Analysis of the compromise between cutting tool life, productivity and roughness during turning of C45 hardened steel

Abstract Tool wear and surface roughness as performance indexes are considered to be the most important in terms of hardened materials’ machinability. The best combination cutting parameters which enhances compromise between tool life, productivity machined quality contribute benefice on production cost, makes manufacturing industry interested it. aim this research is investigate life ceramic machining together with during turning steel C45, focus selection optimal parameter combination. experiments carried out based uni-factorial planning methodology speeds feed rates. results show that mixed suitable for C45 (40 HRC) conclusion it performed well at a speed (200 m/min), (0.08 mm/rev) depth cut (0.3 mm). Additionally, model has been proposed presented very high coefficient determination.
