Abstract

The present study proposed the analysis of cutting forces of GFRP pipes using PCD tool. The filament wound tubes with different fibre orientations are prepared for the purpose of a work specimen. The process parameters used are cutting speed, feed, depth of cut and fibre orientation. The tool forces are measured using KISTLER Dynamometer. The effect of process parameters on Cutting, Thrust and Feed forces is evaluated and the optimum cutting conditions for minimizing the tool forces are evaluated which result in high quality machined surfaces. Second order models have been developed between each of the responses and the process variables using response surface methodology. The predicted values and measured values are in close acceptance, which indicates that the developed models can be effectively used for the prediction of the respective tool forces in the machining of GFRP Composite pipes.
