Planing: Smoothing the surface of each lumber piece and making its width and thickness uniform. Grading: The process of assessing the characteristics of each lumber piece in order to assign its "grade" (quality). The success of wood manufacturing rests on the mill's ability to retain the wood's quality throughout the manufacturing process.
