  • Patent number: 4322191
    Abstract: Apparatus for making the finishing cut on the internal outline of a rough cut female die has two carriages one sliding in one direction upon the other, and the other carriage sliding upon a base at right angles to the first. A male punch comprising a template of the outline to which the die is to be finish cut is mounted on one carriage and the die or workpiece is mounted in an indexing work holder on the other carriage. The template engages a tracer finger fixed relative to the base and to a hacksaw blade which finish cuts the die or workpiece by strokes with the plane of the blade perpendicular to the die surface being cut. The tracer and blade are in common planes to which one carriage moves perpendicularly and the other parallel. The cutter blade and tracer respectively engage the die or workpiece and punch or template in the same direction so that cutting action urges the template and tracer into engagement.
