Nejlep\u0161\u00ed metoda \u0159ez\u00e1n\u00ed pro p\u0159esnou v\u00fdrobu je ta, kter\u00e1 spl\u0148uje po\u017eadovan\u00e9 tolerance, stav hran, v\u00fdkonnost a n\u00e1klady s nejmen\u0161\u00edmi zm\u011bnami procesu v \u010dase, a pro mnoho modern\u00edch aplikac\u00ed v oblasti plech\u016f je to \u0159ez\u00e1n\u00ed laserem. Nep\u0159edst\u00edral bych, \u017ee vyhr\u00e1v\u00e1 ka\u017edou zak\u00e1zku.
