Abstract: In a method of forming a hole on a work piece, a laser beam is directed from a laser head to a predetermined portion of the work piece to form a pilot hole having a first surface condition, and then the predetermined portion of the work piece is punched using a die and a punch having a cross-section greater than a cross-section of the pilot hole. Thus, a finished hole having a cross-section greater than the cross-section of the pilot hole is formed over the pilot hole. The finished hole has a second surface condition, and the second surface condition is formed by transforming the first surface condition by the punch to have a precise dimension.

Abstract: A chamfer cutting device for cuffing packaging materials comprises a die and a knife part which has a plurality of knives. The die can be moved toward the knife part in order to carry out a cut. The knives are arranged individually in the knife part in a force-dependent manner in such a way that their position with respect to the tool plate varies in a defined way as a function of the force produced by contact with the packaging material or the die. In the event of contact between the knife and the die, a force acts on the knife which does not exceed a predefined maximum force. The chamfer cutting device has the advantage that the die can be guided right up to the knives.

Abstract: A method of shearing a thin metal sheet having a thickness of approximately 0.1 mm or less so as to be separated into a product and scrap by a pair of dies. A chamfer or a round having a size of approximately from 5 to 10 times greater than the thickness of the thin metal sheet is arranged at the lip of a first die which presses one portion of the thin metal sheet which is to be scrap. A chamfer or a round is not substantially arranged at the lip of a second die which presses the other portion of the thin metal sheet which is to be a product. A backing material and the thin metal sheet are overlapped so as to be a laminate. The backing material has a thickness of approximately 2 times or more greater than that of the thin metal sheet and is formed of a flexible material having a very small elongation and is soft enough not to substantially prevent the thin metal sheet from being sheared, such as, for example, paper.

Abstract: First and second shaving dies are mounted one above the other and are respectively provided with continuous shaving edges disposed adjacent to contoured annular facial surfaces which draw the shaved material away from the work piece as the shavings are removed by the associated shaving edge.

Abstract: The punch comprises peripheral cutting edges and lateral cutting edges. The peripheral edges cut a slug in the desired shape, for examples, rectangular, square, oval, trapezoidal, D and double D-shaped, etc. while the lateral edges cut transversely from one peripheral edge to an opposite peripheral edge, thereby splitting the slug. Lateral cutting edges provide a dividing line across the working face. Surfaces and cutting edges on each side of the dividing line are similar and canted at opposite angles. Lateral cutting edges and peripheral cutting edges at their juncture provide pyramidal cutting sections which initially pierce the workpiece and initiate lateral slug splitting. This split grows from the slug periphery toward the center. Splitting is complete before a substantial portion of the slug periphery is cut.
