Estimated stress and friction distributions on tool rake face in the medium density fiberboard cutting process

Abstract

This paper presents a model of load distribution on the cutting edge of a tool during machining Medium Density Fibreboard (MDF). A series of cutting tests has been carried out with tools having designated rake face contact lengths. Utilising the experimental data and a mechanics approach developed earlier by the third author, a model to estimate the distribution of stresses and friction on the rake face is developed. The model provides an essential step in the design and development of cutting edge geometry to prevent early edge failure and to control and reduce thermal/mechanical loading of the tool wedge.
