Abstract:
A system for trepanning each hole in a row of at least 2 holes into a work piece comprising;a pulsed laser; a control for positioning and targeting said pulsed laser at each of a plurality of trepanning positions; said control having a first trepanning position wherein said pulsed laser can create a first series of laser trepan cuts corresponding to a portion of said each hole in said row of holes in said work piece during relative movement between said work piece and said pulsed laser, and said control having a second position for creating a second series of trepan cuts as relative movement between said work piece and said pulsed laser occurs and wherein said first series of trepan cuts and said second series of trepan cuts partially overlap to create a portion of each said hole in said row of holes wherein said portion of each said hole has a cross sectional area larger than the cross sectional area of said laser pulse.
