Bandsawing. Part III: stress analysis of saw tooth microgeometry

This article presents a stress analysis of a saw tooth. The analysis aims t o determine the stress distribution for various egde load and varying micro geometry. The analysis is performed on a three-dimensional finite element m odel representing the tip of a saw tooth. The 3D model makes it possible to model the load distribution and study stress distributions across the widt h of the teeth with a sufficient accuracy. The FEM calculations are based o n experimental measurements of the individual cutting forces during bandsaw ing. The previous studies of nonuniform contact relationships on the rake f ace is used when modelling the load distribution. (C) 2000 Elsevier Science Ltd. All rights reserved.
