These machines shape and cut lumber to precise dimensions, using rotary cutters to remove material. A common example is a planer, which smooths the surface of a board to a uniform thickness. Other types create complex profiles, such as moldings, or cut joinery like dovetails and mortises.
Automated shaping and cutting processes offer significant advantages in woodworking, increasing efficiency and precision while reducing manual labor. Historically, achieving such accuracy required extensive hand-tool skills and considerable time. This technological advancement has enabled mass production of consistent, high-quality wood components for furniture, construction, and other applications. Precisely-cut joinery enhances structural integrity and aesthetic appeal.
