Abstract

Today’s demand for a quality product at a low cost requires a closer look at manufacturing operations. The need to optimise manufacturing operations is not just a desire but also a true paradigm for the future of high speed machining. The optimised high-speed machining requires specially designed tooling. This special tooling designed to fit the high-speed applications can yield a multiple increase in productivity and lower cost per part. The quality tooling aspect for high-speed milling has not been investigated rigorously and scientifically. This will involve interactions of many specialists (engineers) in various disciplines, each different than the work of other groups and knowing little about the analysis and software tools available to other groups This paper presents the formulation of an automatic multi-objective multidisciplinary design methodology and algorithm for a high speed milling cutter. At present, tool design is sensitive to changes along the production-realisation time-line. Hence, there is a need for the development of a mathematically rigorous algorithm for high-speed cutting tool design and testing. A proper cutting tool design is achieved by performing a detailed computer aided design of a milling cutter by integrating analysis, solid modelling, optimisation, and finite element analysis. Few researchers have tried to develop such a comprehensive model for a high-speed cutter design. We hope to remove the drawbacks associated with the present approach with this new methodology.

Most researchers have argued that cutting conditions have tremendous
