![]() ![]() Vibration-assisted machining (VAM) was first introduced in the late 1950s, and has been applied in various machining processes, including both traditional machining (turning, drilling, grinding, and more recently milling) and non-traditional machining (laser machining, electro-discharge machining, and electro-chemical machining), and it is now widely used in the precision manufacturing of components made of various materials. ![]() Efforts to enhance machining performance have revealed that machining quality can be improved using the high frequency vibration of the tool or workpiece. However, due to their high hardness and usually low fracture toughness, the processing and fabrication of these hard-to-machine materials have always been challenging. In addition to the aims of achieving tight tolerances and high-quality surface finishes, many applications also require the use of hard and brittle materials such as optical glass and technical ceramics owing to their superior physical, mechanical, optical, and electronic properties. ![]() Precision components are increasingly in demand in various engineering fields such as MEMS, electro-optics, aerospace, automotive, biomedical engineering, and ICT hardware.
