【 摘 要 】

An investigation has been carried out to make use of coir, a natural fibre abundantly available in India. Coir�?�polyester composites were prepared and their mechanical and machinability characteristics were studied. The short coir�?�fibre-reinforced composites exhibited the tensile, flexural and impact strength of 16.1709 MPa, 29.2611 MPa and 46.1740 J/m, respectively. The regression equations were developed and optimized for studying drilling characteristics of coir�?�polyester composites using the Taguchi approach. A drill bit diameter of 6 mm, spindle speed of 600 rpm and feed rate of 0.3 mm/rev gave the minimum value of thrust force, torque and tool wear in drilling analysis.
