Method of manufacturing one or more sharp bodies by wire electro-erosion, semifinished product, fixture, and method of manufacturing a surgical cutting instrument for robotic microsurgery by wire electro-erosion

Abstract

A method of manufacturing sharp bodies by wire electro-erosion includes providing a wire electro-erosion machine and a fixture mounted to the wire electro-erosion machine so that a portion thereof can rotate about a rotation axis which is transverse to a longitudinal extension of the cutting wire. At least one workpiece is mounted to the fixture. An edge to be sharpened of the at least one workpiece is sharpened by a sharpening through cut with the cutting wire on the at least one workpiece. The at least one workpiece is shaped by a shaping through cut with the cutting wire on the at least one workpiece. Between the sharpening and shaping, the portion of the fixture is rotated about the rotation axis thereof by a sharpening rotation angle other than 90°. The sharp bodies may be blades for a surgical cutting instrument for robotic microsurgery.
