The e...

Ultrasonic-assisted grinding processing can effectively reduce the surface roughness and enhance efficiency in of hard brittle materials. However, most common ultrasonic assisted is a type contact where tool directly contacts workpiece, which means that it necessary to accurately control pre-pressure on workpiece. The will inevitably increase complexity device, easy wear workpiece because impro...

Ultrasonic assisted machining is commonly used for of difficult to cut materials especially titanium alloys in ultra-precision (UPM). However, the tool movements ultrasonic unavoidably induce surface damages and side burrs on machined surface, which problem remains unsolved. To address this issue, study, a magnetic field introduced diamond cutting order minimize induced by tool, consequently im...
