Takeyama ( I ) , lkutoku Technical University, and N. lijima, Tokyo University of Agriculture and Technology /Japan Received on January 4,1988 GPa 0.059 GPa 44 GPa 15 GPa 0.25 G P ~ 0.3 -0 .6 ABSTRACT: For a … ULTRASONIC MACHINING Definition: Ultrasonic Machining is a non-traditional process, in which abrasives contained in a slurry are driven against the work by a tool oscillating at low amplitude (25-100 microns) and high frequency (15-30 kHz). It is also known as Ultrasonic impact grinding is an operation that involves a vibrating tool fluctuating the ultrasonic frequencies in order to remove the material from the work piece. Application of Chemical Machining . Ultrasonic machining application method. Ultrasonic Machining is the oldest form of machining process which can be used to machine brittle materials such as glass and ceramics. 6 Machining the glasses, ceramics. 7 Threading. Since the generation of ultrasonic waves, due to its relatively simple, convenient, directional, and concentrated energy, it soon found applications in the OEM machining industry. Generally the tool is pressed downward with a feed force, F. 8 Tapening and Coining. An ultrasonic tool essentially creates many small vibrations that, over time, remove material from the workpiece with which it’s used. 3 Grinding the brittle materials. Process: Ultrasonic machining is a mechanical type non-traditional machining process. @article{Lin2015ApplicationOU, title={Application of Ultrasonic Assisted Machining Technique for Glass-Ceramic Milling}, author={S. Y. Lin and C. Kuan and C. She and W. T. Wang}, journal={World Academy of Science, Engineering and Technology, International Journal of … To learn more about ultrasonic machining and how it works, keep reading. 5 Slicing and Broaching hard materials. 2 Step drilling. O n e emerging technology that is receiving notable attention is ultrasonic-assisted machining, or—more strictly speaking—rotary ultrasonic vibration-assisted machining, sometimes referred to by a simple acronym, UAM. Ultrasonic Machining In ultrasonic machining, a tool of desired shape vibrates at an ultrasonic frequency (19 ~ 25 kHz) with an amplitude of around 15 – 50 μm over the workpiece. Certainly the technology is a winner as evidenced by … Application of ultrasonic in OEM machining industy. Time will tell which one wins. Advantages of Ultrasonic Machining: 1 This process is used for both circular and non-circular holes in very hard materials like carbide, … The earliest application is the defect inspection of metal materials. Applications of Ultrasonic Machining: 1 Drilling round holes of any shape. CHM has been applied in a number of usages where the depth of metal removal is crucial to a few microns, and the tolerances are close. The process involves an abrasive slurry that runs between the tool and the work piece. 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. Wikipedia has published the acronym RUM in its explanation of the process. Overview of Ultrasonic Machining. It is
