Abstract: Developing advanced hard coatings is crucial for improving machining performance. This study evaluates a newly created (Ti,Al,Ta,Ce)N coating realized by physical vapor deposition. Coated cemented carbide inserts were evaluated in dry longitudinal turning on C45E, benchmarked against TiN and (Ti,Al) at two cutting speeds (90 and 300 m·min −1 ) and two feeds (0.1 and 0.2 mm·rev −1 ). Tool wear, cutting forces, and rake face temperatures were monitored. At the cutting parameters of 300 m·min −1 and 0.2 mm·rev −1 , the (Ti,Al,Ta,Ce)N coating outperformed (Ti,Al)N at a tool life of 750 m, reducing tool wear by 73 % and cutting forces by 11 %. • Comparison of three coating materials: TiN, (Ti,Al)N, (Ti,Al,Ta,Ce)N. • Dry longitudinal turning test with two different cutting speeds and feed rates. • Criteria: flank-wear land width, cutting force, rake face temperature. • (Ti,Al,Ta,Ce)N coatings proved to be superior to (Ti,Al)N and TiN coatings.
