Abstract
The paper deals with the evaluation of the static stiffness and strength, which are critical parameters affecting the stability of the machining process but also the safety and durability of the wood cutting tools. Circular saw blade models for the purpose of computer numerical simulation were proposed using finite element methods, and verified in earlier research. Deformation response was observed, depending on the input parameters correlating to the saw blade woodworking conditions. The strength of the saw blade was compared with the different clamping methods and different thickness of the circular saw blade. An article gives a disturbing finding how minor change in the quality of the circular saw blade clamping, specifically one degree of misalignment, leads to critical states and probable cause of damage.

Outputs show the possibility of identifying manufacturing, structural or operational defects in circular saw blades
Summary
Machining processes in general and woodworking processes in particular are complex processes with many interacting factors. The theoretical chip thickness is almost the same as the thickness of the cut chips [3, 4]. The number of teeth of the sawing tool affects its own productivity, surface quality, and sometimes even feed limitation to the tooth [5]
