Selection of Working Frequencies in Complex Plane Motion of Saws within a Woodcutting System

Abstract

Abstract—A woodcutting system based on complex plane motion (translation + rotation) of the saw blades is promising in principle but proves unstable in practice. This may be addressed by selecting working frequencies of the saws that differ from the eigenfrequencies and other parametric frequencies of the system. To that end, those frequencies must be identified. In the present work, a mathematical model of the saw system is derived. Its mass and size are optimized. On that basis, an energy-saving sawing machine superior in performance to comparable machines is manufactured and tested.
