  • Description

    LASER BEAMS, WHICH FOR YEARS HAVE BEEN EXPENSIVE SCIENTIFIC TOYS, ARE NOW BEING DEVELOPED FOR USE IN INDUSTRY. ONE OF THE FIRST HIGH-POWERED CARBON DIOXIDE LASERS TO GO INTO INDUSTRIAL USE ANYWHERE IN THE WORLD WILL SOON BEGIN OPERATING IN AN EDINBURGH PRINTING AND PACKAGING WORKS.

    IT WILL BE USED IN THE CUTTING OF DIES FROM WHICH CARDBOARD CARTONS ARE MADE.

    CARTONS SUCH AS A CAKE BOX OR CIGARETTE PACKET, ARE A COMPLICATED SHAPE - THIS IS CLEAR IF THEY ARE OPENED OUT - AND HAVE TO BE CUT AND HAVE FOLD LINES MARKED IN THEM.

    THESE ARE MADE BY KNIVES SET INTO PLYWOOD. THE MAJOR PROBLEM IS TO MAKE ACCURATE SLOTS IN THE PLYWOOD TO TAKE THE KNIVES. IT CAN TAKE A SKILLED MAN AT LEAST A WEEK TO CUT A COMPLETE DIE - AND IF THE SLOTS ARE NOT EXACT THEY WILL CAUSE PROBLEMS IN THE PRINTING AND PACKING OF THE CARTONS.

    EXPERIMENTS WITH THE LASER SHOW THAT IT CAN DO THE JOB UP TO TEN TIMES FASTER AND MORE ACCURATELY THAN THE METHOD WHICH HAS BEEN IN USE FOR MORE THAN 30 YEARS.

    THE HEART OF THE LASER CUTTING PROCESS IS A CARBON DIOXIDE LASER WHICH EMITS AN INVISIBLE BEAM OF RADIATION. TO USE THE RADIATION AS A MEANS OF CUTTING, THE BEAM IS FOCUSED TO AN INTENSE SPOT. TO INCREASE ITS EFFECTIVENESS THE FOCUSED BEAM IS SURROUNDED BY A STREAM OF HIGH VELOCITY GAS. WHEN THE BEAM AND THE GAS JET STRIKE THE WORKPIECE THEY MAKE A CLEAN CUT.

    THE MOVEMENT OF THE LASER IS CONTROLLED BY EQUIPMENT WHICH CAN FOLLOW A FULL-SCALE LINE DRAWING AND THE LASER CUTS AN INTRICATE PATTERN OF SLOTS IN THE PLYWOOD INTO WHICH THE CUTTING AND FOLDING KNIVES ARE SET. EXPERTS IN BRITAIN ESTIMATE THERE IS A WORLD MARKET FOR AS MANY AS 400 LASERS FOR THIS TYPE OF WORK ALONE.
