Characterization of Arctic Driftwood as Naturally Modified Material. Part 1: Machinability

Arctic driftwood has reached the coast of Iceland for centuries. This material was used by inhabitants island as a building houses, boats, churches and pasture fences. Nowadays, is in furniture industry, finishing internal external walls buildings also artists. The properties differ to that original resource due long-term effects exposure Sea water ice. process can be considered natural modification, even if its effect on various wood potential use are not yet fully understand. research focused comparison cutting forces measured Siberian larch (Larix sibirica L.) from Siberia provenance found Iceland. were determined directly power signal recorded during frame sawing process. A new procedure compensation late/early ratio variation within annual rings proposed homogenize mechanical wood. It allows direct machinability both types investigated (driftwood natural). Noticeable differences normalized force values noticed types, which statistically significant two set feed per tooth. These results provide understanding drifting (natural modification) physical Such modification may influence transformation processes well performance coating systems applied surface.
