  • Control apparatus for a three-dimensional laser working machine and three-dimensional laser working machine
    Patent number: 6617544
    Abstract: The control apparatus for a three dimensional laser working machine teaches a tip position and an attitude of a nozzle and carries out working based on the teaching in a three-dimensional laser working machine having a head structure that a working point does not change when a rotational axis and an attitude axis are rotated. A nozzle direction vector is calculated from current angles of a rotational axis (14) and an attitude axis (16). An angle that the attitude axis (16) changes for constant time is calculated. An angle through which the rotational axis (14) is to be rotated is calculated so that X and Y directions of the nozzle direction vector are kept constant according to an angle change amount of the attitude axis (16), and the rotation of the rotational axis (14) is controlled by the calculated angle.
