Chinese researchers show that ultrasonic vibration-assisted milling can machine hardened internal keyways in bearing steel ...

Traditional electrical discharge machining (EDM) is characterised by a low material removal rate (MRR), a high tool wear rate (TWR), and poor surface finish (Ra), which restricts its suitability for ...

Electrical Discharge Machining (EDM) is a non-contact, thermoelectric process in which material is removed from a conductive workpiece by means of controlled electrical discharges between an electrode ...

As a Hackaday reader, it’s safe to assume you’ve got a better than average understanding of electricity. There’s also an excellent chance you’re familiar with machining, and may even have a lathe or ...
