Abstract
A method and an apparatus for the manufacture of a tool from a blank, such as, a rotational tool which rotates about a longitudinal axis (L) which includes at least one cutting edge and a chip groove. Preferably, the rotational tool is in its operating area in a cross-section thereof radially symmetrical with respect to it's longitudinal axis (L) and manufactured from a cylindrical blank by laser ablation using a laser machining apparatus with a laser scanner with a predetermined pulse area. The laser beam impulses are directed via a positioning arrangement within the pulse area onto a plurality of impact locations disposed along a predetermined pulse path (B). This pulse area is moved, like a tool, along the surface of the blank to form the chip groove and the cutting edge by sublimation of the material.
