Effect of technological parameters and wood properties on cutting power in plane milling of juvenile poplar wood

Abstract

This paper presents the results of experimental measurements aimed at observing the effect of technological parameters (cutting speed vc and feed speed vf ), type of wood (juvenile wood and mature wood) andwood species (aspen Populus tremula, L. and hybrid poplar Populus x Euramericana „Serotina“) on cutting power during plane milling of poplar wood. The results showed the reduction of cutting power with the decrease of cutting speed and feed speed. Lower cutting power was also measured in milling hybrid poplar than in milling aspen. The test also confirmed the effect of different anatomical and chemical structure of juvenile wood in relation to mature wood on different physical and mechanical properties of such wood and hence also on the cutting power in processing juvenile wood.
