  • Method of and apparatus for machining large numbers of holes of precisely controlled size by coherent radiation
    Patent number: 4131782
    Abstract: A method of and apparatus for machining an object wherein a source of coherent radiation is pulse modulated in accordance with the desired machining and the radiation is directed to a deflecting device and deflected to the object which is moving at a controlled speed. Movement of the deflecting device is controlled to deflect the pulsed radiation on the area of the object to be machined regardless of its motion. The method is applied to engrave intaglio printing forms by using gating or pulse length modulation to reproduce accurately the large number of volume variations of the printing cells.
