Abstract

PURPOSE:To stabilize laser light and to improve working accuracy by outputting impulsively the working output of the laser light as functions of the moving speed, material and thickness of a material to be worked and maintaining the low output even while the material is not in movement. CONSTITUTION:A material 13 to be worked is irradiated with a laser light 5 from a laser oscillator 3, via a pulse generator 7, a reflection mirror 9 and a lens 11, and the material is worked by moving a table 15 under numerical control. The moving speed of an X-axis and a Y-axis are detected with detectors 21, 23 and are fed to an arithmetic unit 25 for speed vector, by which the moving speed is synthesized and the actual diagonal moving speed is calculated. The calculated value and material data 27 and thickness data 29 are fed to a pulse converter 31, where the generation mode of the pulse is selectively determined and a command is issued to the generator 7, so that the instantaneous shielding of the laser light 5 and the limitation and passage of the quantity of light are repeated. Therefore, the low output of the extent at which the material 13 is not worked even if it does not move is maintained and the working accuracy is improved with the stabilized laser light.

It is emitted 0.1 (in the right fj direction in Fig. 1), passes through the pulsed light 11 device 7, and is reflected by the anti-body mirror 9.
A table 15, which is fixed on two sides, is used as an X-axis moving means such as, for example, a lead screen 1-h. 1

Velocity Heta 1 Hell calculation c7 Tip 25 combines the moving speeds of the X-axis and Y'FIII force direction to form a composite vector I-le.
The diagonal movement speed of 6 is reached.

The material data 27 and plate material data 29 related to the desired lighting and heating are input into the history + y + T (referring to the desired light and heat suspension). One piece of data is led to the pulse conversion device 31.

The above-described pulse conversion device 31 synthesizes the various data described above to determine the pulse generation mode 3U 411, which will be described later.
