PURPOSE: To exactly cut a small designed shape member by constituting a laser beam pass between a laser beam entrance and a cutting nozzle while connecting a plurality of rotationable segments having mirrors. CONSTITUTION: A laser light supplied from a laser beam feeder 12 through a mirror 14 is transmitted to a cutting nozzle 30 having a focusing lens 33 through a passage in form of articulation having four mirrors 18, 24, 26, 32 arranged inside, connecting each of first and second segments 10, 20 rotated with motors 16, 22. It is desirable to arrange the rotation axis lines of the both segments 10, 20 above mentioned in parallel to each other. Each of the above-mentioned motors 16, 22 is selectively rotationable. They are driven and moved synchronously by a programmable processor to form a desired cutting pattern. |
