Ultrasonic-assisted laser and electrochemical composite multi-energy field collaborative processing system and method

Abstract

The invention discloses an ultrasonic-assisted laser and electrochemistry composite multi-energy-field collaborative machining system and method, and relates to the field of non-traditional machining. A positive electrode of a pulse power supply is connected with a workpiece, and a negative electrode is connected with a tool electrode; the laser beam is totally reflected by the tool electrode to form a plurality of laser beams which simultaneously act on the surface of the workpiece; meanwhile, the electrolyte flows out through the tool electrode and then acts on a workpiece machining area to generate electrochemical reaction, turbid electrolyte continuous liquid flow after the electrochemical reaction is converted into a gas-liquid mixed state by high-pressure low-temperature gas, and therefore a vaporific gas-liquid mixed area is formed on the periphery of the workpiece machining area; and the turbid electrolyte continuous liquid flow is changed into discontinuous vaporific liquid drops, so that the turbid electrolyte continuous liquid flow flowing out of the machining area is prevented from forming a continuous conductive loop to generate impact and electrocorrosion on the periphery of the workpiece machining area. According to the invention, high-efficiency and high-quality processing of large-depth and low-damage deep small holes can be realized.

Description

technical field [0001] The invention relates to the field of composite processing in special processing technology, in particular to an ultrasonic-assisted laser and electrochemical composite multi-energy field cooperative processing system and method. Background technique [0002] Many key components in aero-engines work in the harsh environment of high temperature and high pressure for a long time, which brings severe challenges to the life of components, and the higher the thrust of the engine, the higher the operating temperature. In order to ensure that the core components of the engine can work normally under high temperature conditions, efficient cooling technology must be used to cool the core components, and a large number of film cooling holes is the key structure to ensure cooling efficiency. [0003] The combustion chamber is the power source of the engine and one of the three core high-pressure components. Under severe working conditions such as high temperatur...
