Abstract：Laser machining can be used for almost all engineering materials because of its ability to process simple or complex shaped parts at the macro to micro scale. However, there are still some shortcomings in the laser processing technology, such as thermal stress, processing burrs and thermal damage. Other manufacturing processes such as cutting, electrical discharge machining and electrochemical machining, have the disadvantages of low efficiency and severe tool wear when machining difficult-to-machine materials. Researchers have been looking for methods to solve these problems and hybrid processing is a solution strategy. Hybrid laser processing is a new process that combines one or several processing technologies based on laser processing. In the process of ablating the material, the composite energy field is used to enhance the removal rate, improve the surface integrity, and reduce the thermal damage. Another way is to use the laser as an auxiliary energy field to help improve the machinability of materials and improve the surface quality, increase material removal rate and reduce tool wear. Laser-assisted machining, water-jet guided laser machining and laser composite probe nanofabrication are three typical hybrid laser machining processes. The principles, simulation and experimental research of processing technology are discussed. The improved process efficiency, reduced machining costs and improved quality of machined parts demonstrate the great application potential of hybrid laser machining. Finally, the shortcomings of the current research and the future development direction of the hybrid laser processing technology are pointed out.
