A REVIEW ON MACHINING PROCESS WITH DIFFERENT CHEMICAL ENGRAVING METHODS

Modern high technology industries are facing challenges from machining of non- conducting materials and its cost. Gas films of appropriate thickness are the main requirement in the industry. The formation of the bubbles and the films with constant thickness is desired. To achieve this different parameters are involved in different proportion. The parameters like electrolyte concentration, temperature, critical voltage, speed, composition of electrodes, etc. are playing important role in the machining. Spark assisted chemical engraving is used for micro-structuring of glass. With the proper management of these parameters as per the models discussed by various authors it is possible to get desired machining. To do this it is necessary to have the detail study of the review of the previous valuable work. This brief review will help to get the solution for machining process using different chemical engraving methods and techniques.
