Quality evaluation in production of wooden elements

In the chapter concepts of quality and production were presented. The production-service plant, which is engaged in production frame slats of about 300 designs and colours, of high quality, for frame plants, glass and art galleries, was characterized. These slats are made of wood and ecologically sound materials. The production process of the frame slat depicted technologically was presented. With the use of the Pareto-Lorenz diagram, a hierarchy of nonconformities occurring during the manufacturing process of wooden frame was made. It was indicated that the most frequent nonconformities of the wooden frame are: elements soiled with glue, dirty slat and different colours of individual parts of the frame.
