Compact laser machining head with integrated on-line path control for laser machining of material

A compact laser machining head having integrated on-line path control for laser machining of a material, comprising:

• a sensor providing at least one of geometry recognition and contour following of the material;
• at least one mirror having a mirror housing and mirror holder;
• a predefined interface for a beam guidance system of a machine controlling the compact laser machining head;
• an installation and connection for a water cooling system and a process gas feed used in the laser machining;
• at least one cross jet system arranged on the compact laser machining head;
• an adjustment device and a process gas nozzle for the laser machining head;
• a motor plate having mounted thereon drive devices for providing rotary movement of the sensor, said drive devices including an NC-controlled motor and a gear operable via appropriate current and signal circuits and medium conduits;
• wherein said sensor has a structure completely integrated into the laser machining head and includes a rotary shaft, said sensor being arranged, together with auxiliary devices of the laser machining head, so as to be rotatable around the rotary shaft;
• a protocol memory and a comparator unit are arranged and connected in the laser machining head such that data from said sensor is compared and evaluated, in parallel with a control of the laser machining, with data of said protocol memory in the comparator unit for affecting the laser machining and providing quality control.
