A cylindricity evaluation approach based on the Particle Swarm Optimization (PSO) was proposed. The fundamentals and implementation techniques of PSO were discussed. The problem of cylindricity evaluation was presented and its optimization goal and variables were given. The fitness function of PSO with real number encoding of particles was also described. Taking a example for verifying the feasibility and computation precision of the approach
the computation results show that the PSO-based approach is a useful tool for solving such nonlinear optimization problems as cylindricity evaluation with complicated goal function and more parameters. It is superior to that given by the Least Square Method (LSM) and a little better than or equal to those given by GA-based method and another Minimum Zone Method (MZM). Moreover
the PSO-based approach is not only effective but also simple and easy to implement for computers.
