Wood and wooden materials have been a very popular materials in various projects carried out by man for centuries. Presently, the largest industry sectors where wood is used, are: civil engineering, furniture production. In the wood industry, drying process is one of the most time-consuming and expensive processes used to manufacture wooden and wood-based products. Drying takes place after preliminary sawing process of wet wood logs for sawn timber. Dried wood with a moisture content of 8 to 12% is subjected to re-sawing processes. The wood industry uses various methods of drying wood. The most popular drying processes are in kiln and in vacuum chambers. The simplest method of drying wood is air drying, but this method, also called natural, requires a long time and is highly dependent on weather conditions. A number of scientific studies have shown that the drying processes of wood affect the mechanical properties of wood to a varying extent. One of the main factors affecting the change of wood properties as a result of the drying process is the process temperature. An increase in temperature speeds up the drying process, but at the same time lowers the material properties. The experimental kiln drying method using a warm steam-air mixture significantly reduces the drying time compared to commonly used methods. However, there is a presumption that it also significantly changes the material properties. The aim of the project was to verify whether the method of drying in an experimental kiln using a warm steam-air mixture has an effect on cutting forces and cutting power while sawing process of two the most popular wood species: Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.). The analyzed sawing process was carried out on a frame saw with a narrow kerf PRW15M for perpendicular cutting directions relative to wood fibers. As a result of the tests, a significant difference for the cutting forces values between air-dried wood and wood dried in the experimental kiln was observed. The material properties determined using the Atkins model: fracture toughness R and shear yield stress in the shear plane τγ also had significant differences for the analyzed two species of wood dried by two different methods. During the machinning tests, clear decreases in cutting power values were observed at the beginning and ends of samples of dried wood in the experimental kiln. Such changes were more pronounced for beech wood, but also noticeable for pine. T
