Modelling the aspects of precision and efficiency in laser-assisted jet electrochemical machining (LAJECM)

Laser-assisted jet electrochemical machining (LAJECM) is a hybrid process, which combines a relatively low-power laser beam and an electrolyte jet. Compared to single jet electrochemical machining, LAJECM yields better machining efficiency and precision, especially for small hole machining. The laser beam transfers additional heat on to a specific area of the workpiece area resulting in changed machining conditions. This localisation effect of machining is the key to improving accuracy and efficiency of the LAJECM. This paper presents also a mathematical modelling of the LAJECM process supported by experimental analysis.
