MODELLING OF CUTTING BY MEANS OF FRACTURE MECHANICS

Abstract

The suitability of modern fracture mechanic theory was proved for the estimation of the cutting force and the cutting specific resistance. This paper shows modification of Ernst-Merchant theory and its application for determination some other properties of wood sample. This theory is acceptable for evaluation of shear yield stresses and shear plane angle. Sawing by gang saw machine was used as a process similar to the orthogonal cutting. English oak was used as a machined wood species.
