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 ( ) and an attitude axis ( ). An angle that the attitude axis ( ) changes for constant time is calculated. An angle through which the rotational axis ( ) 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 ( ), and the rotation of the rotational axis ( ) is controlled by the calculated angle.
