Laser and electrochemical machining(LECM)process controls the spatio-temporal coupling of laser and electrochemical energy fields to machine workpiece materials with high surface quality,high efficiency and high precision.LECM combines the advantages of laser processing and electrochemical machining(ECM),and avoids the laser-induced thermal damage.Also,the machining rate of ECM could be improved.LECM has become a research focus in the field of non-conventional machining and advanced manufacturing.The definition and classification of LECM were proposed.The development status of LECM at home and abroad was reviewed including synchronous and sequential LECM processes.The mechanisms of spatio-temporal coupling of laser and electrochemical energy fields were revealed,and the advantages and disadvantages of LECM were clarified.Finally,the challenges and development trends of LECM have been analyzed.
