PURPOSE:To obtain the laser output proportional to the speed of the body to be worked even at the speed increasing and decreasing times and to enable a good working quality by finding a speed command and the output of a laser light by utilizing the command position and simultaneously outputting the respective. CONSTITUTION:The differentiator 101X finding an X axial speed command DX is provided by differentiating the command position PX of the X axis of after the unit time of from a function generator 2 in an X axial shaft driving part 100X. The adder 102X outputting to a driving unit 13X the X axial speed command DSX found by adding the X axial speed command SX fed from an X axial speed computing element 12 and the X axial speed command DX of this differentiator is provided and a feedback control and feedforward control are performed. The differentiators 110X, 110Y differentiating the command. position PX of the X axis of after the unit time fed from the function generator 2, similarly finding X axial speed VX and Y axial speed VY as well and outputting them to a speed computing element 4 are provided on a laser oscillator 7. |
