  • The effect of rip-kerf width on 5/4 Ponderosa pine cutting stock yield

    Creator:
    Rahardjo, Susilowati
    Abstract:
    The moulding and millwork industry consumes large quantities of shop grade lumber which is becoming less plentiful and of a lower quality. This fact has compelled industry to explore the use of new technology to increase product yield. One prospect for increasing yield is the application of thin-kerf sawing technology....

  • The effect of edging red alder lumber on cut stock production

    Creator:
    Schott, Kermit A.
    Abstract:
    It has been observed that edging flitches into lumber unnecessarily reduces the yield of cut stock. This research investigated the yield of cut stock from unedged red alder (Alnus rubra) flitches, and compared it to yields attained from boards subjected to a variety of edging strategies: conventional, light-edging, actual, severe...

  • Three strategies for tree bucking at the harvest site: consequences for the sawmill

    Creator:
    Acker, Timothy A.
    Abstract:
    The timber shortage in the Pacific Northwest is forcing sawmill owners to improve the competitiveness of their harvesting and processing operations. A computer simulation and financial statement analysis were used to compare the processing efficiency and profitability of three bucking strategies: log cost minimization (traditional 40-foot preferred-length logs); hauling length...

  • Filling a rough-mill cutting order using a fuzzy logic controller

    Creator:
    Anderson, James D.
    Abstract:
    Because of their high cost, reducing the number of boards used to fill an order of dimension parts is an important goal in a lumber rough mill. FLCO (Fuzzy Logic Cutting Order) is a computer program that achieves this goal. Using the concepts of fuzzy logic control, FLCO provides a...
