A cutting machine to form a tenon at each end of a piece of timber, which tenon has opposite faces which are inclined both longitudinally and transversely relative to the piece of timber and form hereinafter called skew tenon faces. This tenon cutting machine is of simple and inexpensive construction and uses a pair of circular saws which are simply arranged angularly relative to each other and to the piece of timber to produce both skew tenon faces at each end of the piece of timber by simple bodily displacement of the circular saws transversely of the piece of timber. This machine includes a carriage displaceable in a predetermined direction and carrying the two circular saws, a timber carrying bench to place the piece of timber lengthwise orthogonally to this direction and laterally slanted either way in this direction. The displacement of the carriage causes the saws to cut the two surfaces respectively which are required on either side of the tenon.
