Abstract
A technique for machining work pieces with a laser apparatus and an electric arc apparatus includes generating a plasma gas jet with the electric arc apparatus, generating a laser beam with the laser apparatus, generating an electric arc with the electric arc apparatus, guiding the electric arc through the laser beam to a machined spot inside or on a work piece, and cutting the work piece with the electric arc or the plasma gas jet.
Claims21
A method for machining work pieces with a laser apparatus and an electric arc apparatus, the method comprising:
- generating a plasma gas jet with the electric arc apparatus;
- generating a laser beam with the laser apparatus;
- generating an electric arc with the electric arc apparatus;
- guiding the electric arc through the laser beam to a machined spot inside or on a work piece;
- and
- cutting the work piece with the electric arc or the plasma gas jet.
3 more elements
A machining device comprising:
- a laser apparatus configured to generate a laser beam;
- an electric arc apparatus configured to generate a plasma gas jet;
- and
- a machining head through which the plasma gas jet is aligned from the electric arc apparatus to a machining spot of a work piece;
- wherein the machining device is configured to controllably increase a conductivity of the plasma gas jet by forming a laser-induced plasma channel in the plasma gas jet;
- and
- wherein the machining device is configured to guide the laser beam to intersect the plasma gas jet from outside the plasma gas jet or to guide the laser beam within the plasma gas jet.
