What is it about?
In this article, deformation checks in basic links of big circular saw machines have been made. For this purpose, the maximum deflections in the most endangered cross sections of the main shaft are calculated. The biggest values are compared with the admissible values for the respective material. The normal operation of the big circular saw machine is guaranteed if actual values of the deflections are equal or less than the admissible values.

Why is it important?
Big circular saw machines form a specific class of woodworking machines. In order to saw logs, timber sleepers and beams, circular saw blades with big diameters need to be used. Large static and dynamic loads arise in operating mode. These loads cause large deformations in the main shaft as a result of which the shaft can be destroyed and the circular saw machine to stop working. In this work, to avoid this unfavorable case, an algorithm for carrying out deformation checks of the most endangered cross sections is suggested.
Perspectives
This article was included in a monograph published in 2023 by the author of this study, ISBN: 1-5275-1533-8, ISBN13: 978-1-5275-1533-8. In this monograph, the dynamic processes in big woodworking machines, and more specifically, in big circular saw machines and big band saw machines are investigated and the influence of these processes on the normal operation of these machines is analyzed.
