Comparative Analysis of Conventional and Non-Conventional Optimisation Techniques for CNC Turning Process

This paper describes various optimisation procedures for solving the CNC turning problem to find the optimum operating parameters such as cutting speed and feedrate. Total production time is considered as the objective function, subject to constraints such as cutting force, power, tool–chip interface temperature and surface roughness of the product. Conventional optimisation techniques such as the Nelder Mead simplex method and the boundary search procedure, and non-conventional techniques such as genetic algorithms and simulated annealing are employed in this work. An example is given to illustrate the working procedures for determining the optimum operating parameters. Results are compared and their performances are analysed.
