The influence of drying conditions on wood properties is presented. In the paper the classical approach was used to determine energetic effects (cutting forces and cutting power) of wood sawing process on the basis of the wood specific cutting resistance, material constant. Wood species, namely pine (Pinus sylvestris L.) and beech (Fagus silvatica L.) from the northern part of the Pomerania region in Poland, were subject for determination of wood cutting properties after drying process at various conditions using air at 25 o C, air-steam mixture at 80 o C and steam at 110 o C.
