Sažetak
This paper presents the results of research on power requirements during conventional sawing of oakwood (Quercus Robur L.) on a circular saw for rip-sawing. The major parameters affecting the cutting power are the basic density and the nature of wood species, wood moisture content, feed direction, feed rate, cutting depth and kerf width. The concerned variables in this research were wood moisture content, cutting depth and feed rate. The cutting speed and tool parameters remain constant. Directions of cutting with regard to grain directions were approximately the same for each cutting depth. Cutting power was measured for a specific condition of wood and machine parameters and specific cutting forces were estimated. Specific cutting forces during sawing of green wood are less than specific cutting forces of kiln dried wood and frozen wood. Research results indicate a significant decrease of specific cutting forces in sawing green wood in transversal direction (90º ; ; -90º ; ).
