Each cutter is carried in a carriage mounted in a supporting element which comprises a base displaceable on the frame in two mutually perpendicular directions. The carriage is tiltable around two mutually perpendicular axes for setting the location and angular position of a tenon.These axes intersect each other at an imaginary point coinciding with the root of the tenon, which is i.e. the center of the common attachment plane of tenon and workpiece. The cutters each make a stepwise revolution and a rectilinear reciprocating motion around the root in producing a tenon. Because of this arrangement, the angular setting of the cutter can be quickly adjusted.
