Formation of rectangular tenons by mechanical pressing method.

This paper describes a method of forming elements of tenon joints by local socket pressing, which allows reducing tool costs, waste disposal from area of formation of tenons and getting blank of tenon joints of high quality. The method is based on the introduction of the fibers along the preform of the punch whose profile matches the shape and size of the resulting lugs. Sequence of basic technological operations included in process of manufacturing of tenons by pressing is developed, requirements for operations, range of processing conditions. Wood structure was researched in the deformed zone under the bottom of lugs.
