Question
b) A 10 mm diameter hole is to be drilled in a 5 mm HSS plate by EDM process using RC circuit. The required surface finish is 20 microns. Determine the specifications of a capacitor to be used when supply and discharge voltages are 220 V and 150 V respectively. Use resistance as 50 \Omega and value of constant as 0.4. Also, estimate the time required to complete the job.
