METHOD FOR PRODUCING SMALL BORES IN WORK PIECES BY CHANGING AN OPERATING PARAMETER WITHIN A BEAM PULSE

摘要

A method for producing in particular conical bore holes in work pieces, wherein the contouring and cross-sectional form of the bore hole can be influenced in that one or a plurality of operating parameters are changed, which parameters are elected from the following group: pulse length, beam diameter, beam current, acceleration voltage, beam focusing, deviation of the electron beam from a beam axis, movement velocity of the electron beam over the work piece.
