Cutting Ratio Analysis of Glass Fiber Reinforced Polymer Metal Matrix Composite

Abrasive cut off wheels are commonly used in cutting different types of engineering materials, including both ferrous and non-ferrous materials. The parting wheel consists of hard inorganic abrasive held in place by a binder phase or bond. The most common problem faced during abrasive cut-off operation is the premature failure of the cut off wheel due to its low strength. In the present work woven roving type glass fibre reinforced epoxy resin cut off wheels were developed with silicon carbide (120 grit size) as abrasives and the ball mill setup which is made in aluminium and silicon carbide introduced in this project. The reinforcement of glass fibre with epoxy resin provides high strength to the wheel and prevents the premature failure of the parting off wheel. A mild steel die was used for fabrication of the parting off wheel. The developed wheels were used to cut a wide variety of harder materials die steel, copper and aluminium the wear ratio was measured for each material. The glass fibre reinforced epoxy resin parting off wheels were found to have better cutting ratio for cutting of heavy grade materials. The same experiments were conducted using conventional parting off wheel and comparative study was done.
