Electrochemical machining is a depleting process, based on Faraday’s law of electrolysis. Workpiece works as an anode and tool acts as a cathode. The tool material used is copper and brass. Sometimes stainless steel is also used as a tool material. The tool used is hollow through which electrolyte is pumped at high pressure as…

Following are the parameters which determine the material removal rate and shown graphically below. We can observe the effect of process parameters on material removal rate in Figure 23.4. With increasing frequency of ultrasonic vibration, material removal rate increases. The material removal rate increases with increasing amplitude and the rate of increase in material removal rate increases…

The mechanism of material removal in USM is brittle fracture of the layer work material. A tool of ductile and tough material is used for vibration with high frequency; and a continuous flow of abrasive slurry is used between the vibrating tool and work surface. The impact of vibrating tool on abrasive slurry fractures the…

AJM is used for machining, cleaning, etching, marking, deburring for brittle materials like glass, ceramics, refractories, germanium, silicon, quartz, mica, etc. Following are the frequent applications of AJM.
