  • Specific cutting resistance during sawing wood with narrow-kerf saws depends an the wood moisture content, wood temperature and feed speed among others. Dedicated experiments were carried out on the sash gang saw PRWM15M in order to investigate the details of the frozen wood cutting process. Some experiment samples (Pinus sylvestris) were frozen in the climatic chamber before cutting. Series of cutting were performed on the frozen and room-temperature wood pieces. Values of cutting power during sawing were measured continuously as well as the obtained surface roughness, thickness variations and remain chips. It has been found that obtained values of the specific cutting resistance in the case of narrow-kerf sawing are larger than reference data given in the literature. A decrease in dimensional accuracy of sawn lamella was observed for frozen wood. On the contrary sawn surfaces were smoother (less roughness). Additional analyses were performed to investigate geometrical features of obtained chips A standard mechanical separation of chips into size fractions were curried out with sieve analyses. Alternatively, a camera vision system has been created in order to perform chips analyses with an image processing techniques. The amount of information produced by such system is superior to the mechanical separation method. It provides valuable inputs for the diagnosing of the sawing process. (literal)
