Cutting force and surface roughness evaluation of cryogenic treated inserts for machining en24 grade alloy steel: RSM modelling approach

Cryogenic treatment is the technique of exposing tools/workpieces to cryogenic temperatures to eliminate residual stresses and improve tool performance under specified applications. The current study investigated the impact of cryogenic treatment and coating on cutting tool performance when machining (CNC turning) EN24 steel. The WC grade K20 inserts were obtained and cryogenically treated in a controlled environment for 24 h at 193 °C. Taguchi’s L16 orthogonal array was used in the studies. Turning experiments were carried out under dry-cutting circumstances with three cutting speeds (200, 350, and 500 m/min), three feed rates (0.2, 0.3, and 0.4 mm/rev), and various edge rounds (50 and 80 microns). The machined workpiece’s cutting force and surface roughness were used to assess the machining performance of cryogenically treated and untreated inserts. Inserts that had been cryogenically treated had lower cutting force and surface roughness than untreated inserts. With cryogenically treated coated carbide inserts with a 50-micron edge rounding, the decreased cutting force and surface roughness were determined to be around 1650 N and 0.534 μm, respectively, when cutting EN24 alloy steel at a cutting speed of 500 m/min and a feed rate of 0.2 mm/revolution. Furthermore, the microhardness of the cryo-treated inserts was improved. The integration of cryogenic treatment and coating techniques, resulting in enhanced tool performance and reduced environmental impact, reflects a paradigm shift in machining processes.
