OPTIMIZATION OF CUTTING PARAMETERS FOR MAXIMIZING TOOL LIFE

Optimum use of the cutting tool is a growing need in modem 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 o ptimal values of velocity and feed throughout the cutting process. A t ool life equation has been established from experimental data and the adhesion wear model. Optimization techniques have been used to maximiz e the tool life subject to practical constraints while maintaining a c onstant metal removal rate. The experimental results showed an improve ment in tool life by 30%. (C) 1998 Elsevier Science Ltd. All rights re served.
