Cutting-induced vibration in circular saws

An analytical model of a wood-cutting circular saw blade is developed for t he purpose of understanding the mechanics of a lateral vibration instabilit y known as washboarding. The governing equation developed contains inertial , gyroscopic and stiffness terms based upon the saw plate characteristics w ith the cutting forces being represented by the product of a time-dependent periodic function and the lateral displacement of the saw tooth. A stabili ty analysis of the system is shown to produce predictions that are consiste nt with experimental data. (C) 2001 Academic Press.
