The show's major attraction were woodworking and logging equipment displays by 1,300 exhibiting companies, covering 117,000 square meters. New product introductions continued to showcase programmable computers as a means to lower labor and downtime costs by speeding up machine setup, providing greater machine flexibility, diagnosing machine malfunctions and allowing for centralized control 1. In air defense, the control mode whereby a higher echelon makes direct target assignments to fire units. 2. In joint air operations, placing within one commander the responsibility and authority for planning, directing, and coordinating a military operation or group/category of over machines linked together as automated manufacturing lines. This trend was particularly pronounced in the area of panel processing, where many machinery manufacturers demonstrated just-in-time production concepts for reducing raw material inventory costs. As computers become more prolific to the industry, they are also becoming more accessible, being integrated into more cost affordable, down scaled versions of machines. There was also greater emphasis placed on machinery health and safety considerations, including improved dust collection efficiency for panel saws. This article highlights some of the technical developments in panel processing. Next month's article will focus on machinery for solid wood processing Wood processing is an engineering discipline comprising the production of forest products, such as pulp and paper, construction materials, and tall oil.
