ABSTRACT:
A method and apparatus for trepanning a workpiece by controlling laser energy on variable diameters thereof includes the method steps of directing a collimated beam of energy against the workpiece and shifting and rotating the collimated beam so as to orbit a focal point on the workpiece to change the trepanning diameter. Apparatus for practicing such method includes a lens housing with a lens holder which is easily removable and is also positionable with respect to a reference axis by a pneumatic pressure acting against a spring loaded stop and further including means for rotating the lens housing on the reference axis to orbit the focal point of a collimated beam of laser energy about the reference axis to vary the trepanning diameter.
