Control and positioning method of a beam or jet for machining a workpiece

(-- A summary 57) and the purpose a beam or a jet style -- especially -- the continuous surveillance of a laser beam, and a position -- realize the method and equipment which can carry out the compensation to a law and a basic position easily, and can carry it out at very slight cost. Composition The detection result (value) obtained by presetting or the 1st sensor (7) of this 該 about the regulation position of a beam or a jet style, Compare the detection result (value) of the 2nd sensor (9) about the actual position of a beam or a jet style (3), and this comparison, It is that the beam or the jet style (3) was rectified by the basic position when it was made to be made under consideration of the relative displacement depending on the speed between a beam, or a jet style / workpiece and a deviation was between an actual position and a regulation position.
