Abstract: The present invention is a die positioning system for use in positioning mobile or fixed dies. The system includes a pair of key bars, a pair of key disc inserts, a set of key discs, and a set of disc backers. The key bars and key discs serve to offset manufacturing dies or die holders. Using key bars and/or key discs from different pairs of key bars and/or sets of key discs also allows for precise angulation of the dies or die holders. The key discs are held in place between the die and die holder, or between the die holder and key base, by the key disc inserts and angled (if feasible) by the disc backers. The key bars, located between the key disc inserts and the die or die holder allow additional offset of the die or die holder. The solid, stacked configuration of the key bars and key discs prevents the die or die holder from gradually or suddenly losing its positioning.

Abstract: A lathe leveler for centering a cutting tool in relation to a cylindrical work piece includes a first leveling arm having a first contact point disposed adjacent a distal end of the first leveling arm, a second leveling arm having a second contact point disposed adjacent a distal end of the second leveling arm, a leveling gage, and a leveling plate having a cutting tool receiving surface positioned parallel to a horizontal axis of the leveling gage and on a same plane as a midpoint of the first contact point and the second contact point. The leveling arms and leveling plate are dimensioned and configured such that the cutting tool receiving surface is centered in relation to the work piece when the first and second contact points are in contact with one of the inner surface and outer surface of the cylindrical work piece and the leveling gage is centered.

Abstract: A bar notch (3) in the side of a side member (1) and a shaping cut (4) at the end of a cross member (2) for the bar jointing of a side member (1) with a member (2) in workpieces of wood, plastics or MDF—medium density fiberboard—produced by a punching or shearing operation consisting of a first step—a preliminary cut—and a second step—a final cut. A machine for implementation of the cutting operation comprises a knife head (9) for two side knives (10) and a nose knife (11), a table (14) and a rest (13), a first set of adjustable guide members (17) that can set the position of the knife head (9) in relation to the workpiece (1) or (2) which is to be processed, a second set of adjustable guide members (23) for setting of the mutual distance between the cross member notches (3) and a third guide member (29), which can serve as an end stop for the end of the cross member (2) during the shearing process of a cross member shaping (4).
