Ultrasonic machining is precise enough to be used in the creation of microelectromechanical system components such as micro-structured glass wafers. [8] In addition to small-scale components, ultrasonic vibration machining is used for structural components because of the required precision and surface quality provided by the method.
Machining is a form of subtractive manufacturing, [1] which utilizes machine tools, in contrast to additive manufacturing (e.g. 3D printing), which uses controlled addition of material. Machining is a major process of the manufacture of many metal products, but it can also be used on other materials such as wood, plastic, ceramic, and ...
Precision grinding would take more than 200 s to do the same. CFG has the disadvantage of a wheel that is constantly degrading, requires high spindle power (51 hp or 38 kW), and is limited in the length of part it can machine. [1] To address the problem of wheel sharpness, continuous-dress creep-feed grinding (CDCF) was developed in 1970s. The ...
Precision engineering is a subdiscipline of electrical engineering, software engineering, electronics engineering, mechanical engineering, and optical engineering concerned with designing machines, fixtures, and other structures that have exceptionally low tolerances, are repeatable, and are stable over time.
Norio Taniguchi (谷口 紀男, Taniguchi Norio, May 27, 1912 – November 15, 1999) was a professor of Tokyo University of Science.He coined the term nano-technology in 1974 [1] to describe semiconductor processes such as thin film deposition and ion beam milling exhibiting characteristic control on the order of a nanometer: "Nano-technology"
Pedal-powered grinding machine, Russia, 1902. A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding. It is a type of material removal using an abrasive wheel as the cutting tool. [1] Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

Diamond flycutting. Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits.
