A machinability study of polymer matrix composites using abrasive waterjet cutting technology

Abstract

Abrasive Waterjet (AWJ) cutting is an emerging technology for material processing with the distinct advantages of no thermal distortion, high machining versatility, high flexibility and small cutting forces. In this paper, an experimental investigation of the machinability and kerf characteristics of polymer matrix composite sheets under abrasive waterjets is presented. It shows that this unique ‘cold’ cutting technology is a viable and effective alternative for polymer matrix composite processing with good productivity and kerf quality. Plausible trends of kerf quality with respect to the input parameters are discussed, from which recommendations are made for process control and optimization.
