Ultrasonic machining is a method of grinding that uses an abrasive liquid rather than direct tool contact. })(jQuery); Junying Metal Manufacturing has developed high-level manufacturing technique in At the beginning we'll start with the definition, then we dive into the steps of die-casting, Types, die casting defects with the solution. This process is best suited for brittle materials. production fields of machining. This machines having great properties like: Ultrasonic machining is Mechanical machining methods. The tool has the same shape as the cavity to be machined. Ultrasonic machining is a non-traditional machining process. USM is grouped under the mechanical group NTM processes. An abrasive gun is used to supply an abrasive slurry, which is a mixture of abrasive grain and the water in between tool-workpiece interface under a definite pressure. Ultrasonic Machining (USM) is changing the manufacturing 1) Welding method: The welding head vibrating at ultra-high frequency of ultrasonic waves under a moderate pressure causes the frictional heat of the joint surfaces of the two plastics to be instantaneously melted and joined. When very frequency vibrations are applied on to the tool, the tool is vibrating at a very high frequency. Working Principle of ultrasonic Machining: Let us know if you liked the post. Working on machines is not hazardous, provided care is taken to shield ultrasonic radiations from falling on the body. It uses a shaped tool, high frequency mechanical motion and abrasive slurry The term ultrasonic describes a vibratory wave having frequency larger than upper Frequency limit of human ear. In this article first, we will see the Definition, How it's Work after that I'll also show you the Applications, Advantages, […], In the field of mechanical engineering, the Extrusion Process is widely used by the engineers to form an object which has a fixed cross-sectional area. In ultrasonic machining, the tool moves vertically or orthogonal to the surface of the part and fluctuate at the ultrasonic frequencies, the vibrations generated by the tool will project micro-sized abrasive particles to the part at a high speed, the particles mix with water or other liquids to form a slurry, which flowing between tool and workpiece, helps to grind away material from the surface of the piece. (function ($) { In this machining process a focus stream of abrasive particles are forces to impinge on work piece at high velocity. The tool should be designed as like when the operation is performed does not lead to brittle fracture of it. It is a free resource site for Mechanical Engineering aspirants. Plasma arc machining b.
