A numerical model, developed in Part I of this paper, is used to investigate the effect of band saw variables on cutting accuracy. The effect of blade parameters upon tooth tip stiffness is examined and the response of a blade cutting through an idealized knot is considered in detail. In particular, the effect of side clearance is examined. Using a cutting force model based upon a Brownian function representation of the cutting forces, nondimensional variables are developed that govern the cutting accuracy predicted by the model. Finally, the question of choosing an optimum side clearance, to minimize fibre loss is considered.
