چکیده

This research work presents the results of an experimental investigation of cryogenically treated, coated and uncoated tungsten carbide cutting tool inserts in turning of AISI 1040 steel. Three different tungsten carbide inserts coated with aluminum chromium nitride (AlCrN), titanium nitride (TiN) and uncoated WC were taken and treated cryogenically. Experiments were performed to evaluate the cutting forces and tool wear at different machining conditions. ANOVA was performed to identify the effect of the input parameters on response variables. Results indicated that treated TiN coated tools have lower tool wear and cutting forces followed by treated AlCrN coated and treated uncoated tools. It has been observed that cutting forces increased with the increase in feed, depth of cut and decreased with increase of cutting speed in all cases. However Flank wear increased with the increase in depth of cut, cutting speed and feed.
