Abstract: This paper presents an initial research into the sawing scheme drawn up by computers in sawmills. With the help of the widely accepted BASIC language, and the principle of maximum lumber recovery, a program has been worked out for the widely adopted through-and-through sawing and slabbed cant sawing. It can not only provide a better basis for the planning of production and management in sawmills, but also save a lot of time. It can also predict the situation in production and help increase lumber recovery.
