Application of Response Surface Method to optimize Waterjet cutting process parameter of Glass Fiber Reinforced Polymer matrix laminates 2019-28-0153
Waterjet machining is an advanced machining technique because of its versatile unconventional cutting for wider range of materials. Waterjet machining is especially useful in precise cutting of advanced materials like Fibre Reinforced Polymers (FRPs) comparative to conventional machining methods. The conventional machining methods results in release of high amount glass fiber dust which leaves the work environment unsafe for the workers. If the material dust inhaled can lead to respiratory diseases as well. An analysis of the cutting performance of Waterjet machining is presented based on an experimental investigation on fiberglass reinforced laminates fabricated using hand layup technique. It is shown that with a good combination of cutting parameters such as nozzle traverse speed, waterjet pressure and Stand-off distance a cutting performance can be achieved. Plausible trends of kerf quality and machining time with respect to the waterjet pressure, nozzle traverse speed and nozzle stand-off distance are analyzed. The kerf quality and machining time will be optimized using DOE techniques for achieving a proper machining characteristics and faster completion of the work. The RSM a well renowned technique is used to optimize the process parameters.
