Abstract
1,087,534. Cutting by lasers. KEARNEY & TRECKER CORPORATION. May 26, 1966 [Aug. 18, 1965], No. 23736/66. Heading B3V. [Also in Divisions G2, G3 and H1] A laser cutting machine for metal workpieces comprises a laser 39 which produces a collimated light beam 37 of circular crosssection, a beam shaping means 42 for changing the beam cross-section into rectangular form 45, and a movable work support 17. The latter is movable along guides 13, 14 by a reversible servomotor 18 which also drives a tachometer generator 19. The laser 39 is mounted on a cutting head 24 movable transversely by a reversible servomotor 32 which also drives a tachometer generator 33. The generators 19, 33 provide feed-back signals to the servo control system 55 which is itself controlled by a tape in cabinet 52 to provide both speed and position control signals. The laser 39, Fig. 4 (not shown), comprises a ruby rod (176) with a semi-transparent reflector (181) at one end and beam expanding lenses (182), (183) at the other end co-operating with a totally reflecting mirror (191). The laser is energized by a flash lamp (194) supplied from power source (59) controlled by the tape. Alternatively the laser may comprise a simple ruby rod with a total reflector at one end. The beam is changed into rectangular crosssection by the shaping means 42 comprising diffusing lenses (90), (91), Fig. 2 (not shown), a copper mask (115) with cooling fins (62) and converging lenses (111), (112). The beam shaping means 42 is mounted for rotation in bearings (70), (71) for maintaining the long edge of the rectangular beam in alignment with the cutting direction. Rotation is effected automatically by a servomotor 47 controlled by a resolver 50 which receives signals through valve amplifiers, Fig. 5 (not shown), from the tachometer generators 19, 33.
