Rolling mills for rolling of steel may differ in many aspects with each other. The mill rolls steel materials of different cross-sections, sizes and qualities and in material conditions which are either hot or cold. All the rolling mills have rolls for the rolling of materials which are fitted in roll stands. When these rollers are affected to heavy cyclic loads or cracking of rolling elements they may be broken. These broken rollers are replaced with new rollers or existed old rollers after required machining operations. CNC machines are used to produce finished rolls from cylindrical form or used to redress the existed rolls. These rolls are produced through straight turning, taper and circular machining. In this work spindle speed, feed rate and depth of cut are taken as the machining parameters in turning of rolls. The machining time (Mt) and Tool Life (Tl) are taken as objective function. This project work aimed at the optimization of turning parameters for the minimum machining time and maximum tool life by using Genetic Algorithm (GA). This project applies Taguchi’s design of experiment methodology and regression analysis (in MINITAB17) for optimization of process parameters in turning of cast iron rolls using tungsten coated carbide insert. Experiments have been carried out based on L9 orthogonal array design with three process parameters namely spindle speed, feed rate and depth of cut for machine time and tool life. The mathematical models have been developed for individual’s response using regression analysis. Genetic Algorithm (in MATLAB R2013a) is used for the optimization of objectives to indicate that the significance of three process parameters.
