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 ...
Small ultra-precision and diamond turning lathes exist, but have little in common with a desktop-style micro lathe other than form factor. The smallest CNC micro lathe was made by researchers at the Mechanical Engineering Laboratory of Japan ’s Ministry of Economy, Trade and Industry and Olympus Optical Co.
Taniguchi started his research on abrasive mechanisms of high precision machining of hard and brittle materials. At Tokyo University of Science, he went on to pioneer the application of energy beam techniques to ultra precision materials processing; these included electro discharge, microwave, electron beam, photon (laser) and ion beams.
The company was founded in 1930. The company's original name, American Machine and Metals, was changed to AMETEK in the early 1960s, reflecting its evolution from a provider of heavy machinery to a manufacturer of analytical instruments, precision components and specialty materials. [5] AMETEK has been ranked as high as 402 on the Fortune 500.
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.
The Moore family firm, the Moore Special Tool Company, independently invented the jig borer (contemporaneously with its Swiss invention), and Moore's monograph is a seminal classic of the principles of machine tool design and construction that yield the highest possible accuracy and precision in machine tools (second only to that of ...
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 ...
