Provenance dependent optimization of Pine timber processing in wooden bad frame production

Pine timber from different European localizations and intended for the production of continental bed frames at Sun Garden Polska was analyzed. One of the available methods of processing sawn timber into intended friezes (frame semi-finished products) is its transverse or longitudinal-transverse cutting into ready-made elements and into cutouts of appropriate quality intended for joining lengthwise by means of finger joints. In the next stage of production, such boards are re-sawn into ready frame semi-finished products. As part of the research, the length shares of the quality classes KW, KS and KG in boards were determined. From the point of view of the final product, each of the frame components must meet the appropriate quality requirements, and hence the need to optimize the cutting not only based on maximizing the material efficiency of the process, but also taking into account the needs of elements in specific qualities. Merely increasing the quantitative efficiency in the production of dedicated wooden frames is pointless, because the performance indicators do not correspond to the fulfillment of production orders, leaving an excess of some components and a shortage of others. For this reason, it was proposed to parameterize the optimization process taking into account the filling of order baskets and the feedback based on them for timber of different provenances.
