Hybrid Machining Processes (HMP) consist of two different types of machining processes which are applied at the same time in the machining zone. These processes are applied for machining of various advanced materials of complex shapes and sizes. One of the important HMP is Laser Assisted Jet Electrochemical Machining (LAJECM) where a laser beam of low power and a jet of electrolyte are coaxially focused through a nozzle on a particular machine zone. Thus it eliminates the stray machining effect of ECM process. Machining zone temperature as well as electrolyte current density is increased by laser. Thus electrochemical dissolution rate and MRR are increased. In this process, jet of electrolyte is used as tool which eliminates the complex tool design problem of stand-alone ECM process. Laser assistance in ECM process improves precision, accuracy, surface quality and also productivity. Various researchers have performed their research work on LAJECM. This article focuses on various aspects and implementations of LAJECM.

Thus it eliminates the stray machining effect of ECM process. Machining zone temperature as well as electrolyte current density is increased by laser. Thus electrochemical dissolution rate and MRR are increased. In this process, jet of electrolyte is used as tool which eliminates the complex tool design problem of stand-alone ECM process.
