Summary:

This monograph presents research related to big woodworking machines and, in particular, research related to big circular and big band saw machines. These machines are characterized by their size, which creates problems both in their design, and during their normal operation. Big static and dynamic loads occur during the technological process of sawing. These loads give rise to deformations of the main links of the machines. The final result is increased electricity consumption. The monograph includes four chapters. In the first chapter, the influence of static and dynamic loads on the main links of machines is investigated. In the second chapter, transverse vibrations and spatial deformations of machine shafts are investigated. In the third chapter, deformation checks are made, which can prevent damages in machines. In the fourth chapter, the kinetic energy losses of the two classes of machines are investigated. The main purpose of these studies is to propose optimization solutions that lead to the minimization of energy losses.
