PROCESS AND DEVICE FOR MACHINING WORKPIECES USING A LASER BEAM

In a process for machining workpieces using a laser beam, optical and/or acoustic signals generated in a machining region are recorded and used to obtain actual values which are compared with corresponding reference values of a processing diagram specific to the material and to the machining.

More Information
Summary:In a process for machining workpieces using a laser beam, optical and/or acoustic signals generated in a machining region are recorded and used to obtain actual values which are compared with corresponding reference values of a processing diagram specific to the material and to the machining. The results of the comparison are used to control the machining process by influencing it in a predetermined manner. In order to influence the machining region with a process gas in an appropriate and cost-effective manner, process gas is supplied to the monitored machining region in which the optical and/or acoustic signals are recorded, and the type of process gas and/or at least one gas supply parameter are continuously adjusted.
