Abstract |
Abstract- The work tries to investigate the surface characteristic of microwave drilled surface. The influence of heat concentrated by a concentrator over the perspex (PMMA) specimen is studied. Perspex is widely used as a substitute of conventional glass applications. Vicker hardness (Hv) is analyzed for blind and through hole. The three different surface affected by heating are identified as pile up, heat affected and normal zone. Different hardness values are experienced in different zones. A COMSOL software analysis is also used to show the formation of heat zones over the specimen surfaces. The experimental observations are similar with the simulated trials. The Hv values at heat affected zone were found different for through and blind hole. The result helps to control the microwave power for less variation of Hv during the process. | |||||||||
