【Abstract】 In order to investigate the effects of wood species and wood moisture contents on cutting force (P), sawing power (N) and specific power (K) of circular rip sawing, Nine wood species grown in northeast district in China were tested at constant cutting speed and feed speed. Quantitative comparison among the cutting indexes of the 9 species was made, and the defference between the effects of moisture contents of Picea jezoensis and Tilia amurensis was illustraed and discussed.更多还原
