Material- and energy-saving belong to the basic requirements which are imposed on the contemporary manufacturing processes. Since realization of those processes gives measurable profits not only economical but also ecological. In case of wood sawing with circular saw blades material- and energy-savings are dependent on total overall set of teeth (theoretical kerf) and teeth position accuracy in relation to the workpiece. Hence, obtaining a decrease of both raw material and energy losses the use of narrow-kerf saw blades, an increase of sawing accuracy, and besides a reduction of spacing, in the case of sawing with a gang of circular saws, are required. However, an intention materialization of those requirements in the case of sawing with circular saw blades in a quite difficult issue and depends on many factors. The carried out detailed analyses concerning ways of chip transportation in the kerf slot, saw blade stiffness, saw blade movement and workpiece feeding accuracy are the proofs of those inconvenient technical problems for sawmills. Not till then the whole system of sawing fulfils defined requirements the realization of economical wood sawing with circular saw blades seems to be practical.
