Multiobjective optimisation technique using Design-Expert software was applied to obtain solution based on desirability function that simultaneously optimises the variables and the responses. A desirability function of 0.811 gives the optimised solution. The experimental and predicted results showed minimal errors in all the measured responses. {\^A}{\copyright} Published under licence by IOP Publishing Ltd.}, author = {Achara, B. E. and Mohammed, B.
