Optimization of cutting parameters for maximizing tool life

Optimum use of the cutting tool is a growing need in modern industries since the cost of production is directly affected by this. This paper presents a new approach for improving the cutting tool life by using optimal values of velocity and feed throughout the cutting process. A tool life equation has been established from experimental data and the adhesion wear model. Optimization techniques have been used to maximize the tool life subject to practical constraints while maintaining a constant metal removal rate. The experimental results showed an improvement in tool life by 30%.
