ادامه مطلبUltrasonic Assisted Grinding Process With Minimum Quantity. Aug 15, 2016 This process is called ultrasonic assisted grinding (UAG). The use of ultrasonic vibration in material removal, first time showed by A.L. Loomis and R.W. Wood in a paper in 1927, and the first patent granted to L. Balamuth in 1945 (Bhaduri et al., 2012).
ادامه مطلبUltrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. The tool travels vertically or orthogonal to the surface of the part at amplitudes of 0.05 to 0.125 mm (0.002 to 0.005 in.).
