Claim 1
Independent Claim
140 words
THE METHOD OF PRODUCING PROFILE MILLINGS BY MEANS OF A BEAM OF CHARGE CARRIERS, THE WORKING CROSS SECTION OF WHICH IS SMALLER THAN THE SURFACE OF THE REGION OF MATERIAL TO BE WORKED, WHICH COMPRISES FOCUSSING THE BEAM ON THE SURFACE TO BE WORKED WITH AN INTENSITY SUFFICIENTLY HIGH TO VAPORIZE THE MATERIAL, PULSING THE BEAM INTERMITTENTLY, AND CONTINUOUSLY DEFLECTING THE BEAM IN REPEATED PASSES OVER THE SURFACE WITHIN THE LIMITS OF THE REGION OF THE MATERIAL TO BE WORKED IN SUCH A MANNER THAT THE ENERGY CONCENTRATION IS HIGHEST ALONG THE EDGE LINES OF THE REGION, THAT AN AMOUNT OF ENRGY SUFFICIENT FOR VAPORI ZATION OF THE MATERIAL IS DIRECTED AT EACH POINT OF SAID REGION, AND THAT THE POINTS OF IMPINGEMENT OF THE BEAM PULSES ARE DISPLACED WITH RESPECT TO THE POINTS OF IMPINGEMENT DURING THE PRECEEDING PASS.
