Abstract

A technology feasibility study for reducing lumber thickness variation was conducted from April 2001 until March 2002 at two sawmills located in the southern U.S. A real-time statistical process control (SPC) system was developed that featured Wonderware human machine interface technology (HMI) with distributed real-time control charts for all sawing centers and management offices. The thickness data were distributed to all PCs at the instant of measurement by way of wireless transmitters attached to calipers.
