Abstract: In recent times, there has been a dramatic shift in the manufacturing techniques. The levels of automation and digital interfacing, particularly in machining, have increased to higher planes. Constantly growing demand and machining complexity has led to incorporation of a variety of methods to improve the machining accuracy and productivity. This paper investigates various conventional methods such as Taguchi method, RSM, linear programming, etc. and non-conventional methods like genetic algorithm, PSO, simulated annealing, etc. in the optimization of machining parameters and toolpath. The paper also highlights the advantages and drawbacks of different methods to set future scope of optimization in machining.
