ULTRASONIC MACHINING. Definition: Ultrasonic Machining is a non-traditional process, in which abrasives contained in a . In ultrasonic machining, tool of desired shape vibrates at ultrasonic frequency ( 19 to. 25 kHz. ) with an amplitude of 15-50 ... abrasives and method of introducing the slurry has also effect on MRR.
The introduction of sintered diamond tools has enabled to overcome the problem, giving a wear ratio of 0.01 when machining soda glass. However, tools in sintered diamond are limited to a minimum diameter of 15 µm since they are fragile and tend to break during machining. Rotary ultrasonic machining (RUM) is a hybrid.

Keywords: aluminium foam; composite; ultrasonic milling. 1. Introduction. Cellular metals such as foamed metals are attractive material for light weight design. Several types of metallic foams have been produced [1,2] since the first invented “foam-like mass of metal” in 1948 . A number of metals and alloys can be foamed.
Unlike other non-traditional machining processes, such as laser beam and electrical discharge machining, USM process does not thermally damage the workpiece or introduce significant levels of residual stress, which is important for survival of materials in service. For having enhanced machining performance and better.
