advanced machining processes nontraditional and hybrid machining processes pdf

In Chap. 3, the chemical machining processes such as chemical milling
(CHM), photochemical machining (PCM), and electrolytic polishing (EP)
are discussed. In these processes the material is mainly removed
through chemical dissolution (CD) occurring at certain locations of the
workpiece surface.

Chapter 4 deals with electrochemical machining (ECM) and related applications that include electrochemical drilling (ECDR), shaped tube electrolytic machining (STEM), electrostream (ES), electrochemical jet drilling (ECJD), and electrochemical deburring (ECB). The electrochemical dissolution (ECD) controls the rate of material removal. Machining processes that are based on the thermal machining action are described in Chap. 5. These include electrodischarge machining
(EDM), laser beam machining (LBM), electron beam machining (EBM), plasma beam machining (BPM), and ion beam machining (IBM).

of these processes, material is removed from the workpiece by melting
and evaporation. Thermal properties of the machined parts affect the
rate of material removal.

Hybrid electrochemical machining processes are dealt with in Chap. 6. Some of these processes are mainly electrochemical with mechanical assistance using mechanical abrasion such as electrochemical grinding (ECG), electrochemical honing (ECH), electrochemical superfinishing (ECS), and electrochemical buffing (ECB). The introduction of ultrasonic assistance enhances the electrochemical dissolution action during ultrasonic-assisted ECM (USMEC). Laser beams activate electrochemical reactions and hence the rate of material removal during laserassisted electrochemical machining (ECML).

Chapter 7 covers the hybrid thermal machining processes. Electrochemical dissolution (ECD) enhances the electrodischarge erosion action (EDE) during electroerosion dissolution machining (EEDM). Mechanical abrasion encourages the thermal erosion process during electrodischarge grinding (EDG) and abrasive-assisted electrodischarge machining (AEDG and AEDM). Ultrasonic assistance encourages the discharging process during ultrasonic-assisted EDM (EDMUS). Triple-action hybrid machining occurs by combining both electrochemical dissolution (ECD) and mechanical abrasion to the main erosion phase during electrochemical discharge grinding (ECDG)
