Description

technical field

[0001] The invention belongs to the fields of laser processing and composite electric discharge processing for special processing, and more specifically relates to a device and method for ultrashort pulse laser-induced plasma-assisted composite electric discharge processing under the action of a magnetic field. Background technique

[0002] With the development of modern industry, the demand for small-scale products in many industrial sectors is increasing, and there are more stringent requirements for the dimensional accuracy and surface roughness of the products. Compared with traditional processing methods, special processing is through non-mechanical contact. Instead of generating macroscopic chip force, materials are removed through non-mechanical energy (electricity, magnetism, light, heat, and chemistry), which can more easily meet processing needs and meet the sustainable development concept of energy saving and environmental protection.
