Experimental investigation of optimized machining time (drilling time) and surface roughness of drilled holes of particle board (PB) and medium density fibre board (MDF) with various cutting environments

Abstract

Particle board (PB) and Medium Density Fibre Board (MDF) wood composites are widely used in building and furniture industries. Drilling process used in assembly of panel products. The input parameters used causes drilling damages and must be avoided. The experiments are achieved and the inspiration of input parameters on the output response has been studied and analysed. It is revealed that cutting parameters and tool size have major effect on delamination. In this article, an attempt has been made to predict and minimize the delamination in drilling of Particle Board and Medium Density Fibre Board. The experiments are carried out based on Orthogonal Array with feed rate and cutting speed as process parameters. The optimization results showed that the combination of low feed rate with high cutting speed is necessary to minimize delamination in drilling of MDF.
