The differential impact of a density of Polish pine wood on cutting forces with its origin region taken into consideration

The differential impact of a density of Polish pine wood on cutting forces with its origin region taken into consideration. In the article the dependence of cutting forces in a function the density of wood with regard to the wood origin are presented. Samples used in experiment were with Scotch pine (Pinus sylvestris L.) originating from four provenances in Poland (Figure 1). Wood density was measured by two methods: stereometric method (global density) and radiometric method (local density). Stereometric method consists in measurements the volume of the sample by determination of the various dimensions (length, width, height), and weighting of the sample mass. Estimation of the local density was after experiments of cutting using a nondestructive methods of radiometric developed IVALSA \ CNR. Measurement of cutting forces made during the empirical cutting a samples of wood on the saw frame PRW15M.
