Abstract: This paper presents development of mathematical model for prediction of heat affected zone (HAZ) and optimisedparameters for air plasma cutting operation on AISI 6061 aluminium alloy. Experimental and predictive values from RSM arefound of same trend. Partial swarm optimisation (PSO) was employed to optimise cutting parameters. Deviation of HAZobtained by optimised HAZ model is 2.72%. Optimum cutting parameters for minimum HAZ are: output current, 100 A;stand-off gap, 1 mm and pressure, 620.52 kPa.
