The simplicity of the process makes it economical for a wide range of applications such as: Ultrasonic machining has many advantages in manufacturing industries. Applications of Machining Process: The applications of machining process are as follows. So a high frequency high voltage power supply require for this process. Ultrasonic 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 method is employed to machine hard and brittle materials which are either electrically conducting or non-conducting. An ultrasonic tool essentially creates many small vibrations that, over time, remove material from the workpiece with which it’s used. This is all about ultrasonic machining principle, working, equipment’s, application, advantages and disadvantages. As we know, transducer is a device which converts electric single into mechanical vibration. The maximum speed of penetration in soft and brittle materials such as soft ceramics are of the order of 20 mm min, but for hard and tough materials, the penetration rate is lower.

Highly accurate profiles and good surface finish can be easily obtained. Ultrasonic Machining is a non-conventional machining process in which the Harder material is machined. Ultrasonic machining is non-traditional machining process which is used to machine brittle and hard material. Since laser machining is a thermal process, heat-affected damage does occur and can have a negative impact on the end use, especially in high-reliability applications. We and our partners share information on your use of this website to help improve your experience. Horn which is also known as tool holder, transfer this amplified vibration to tool which makes tool vibrate at ultrasonic frequency. Water Jet Machining (WJM) also called water jet cutting, is a non-traditional machining process in which high-velocity jet of water is used to remove materials from the surface of the workpiece.WJM can be used to cut softer materials like plastic, rubber or wood. ULTRASONIC MACHINING PROCESS (USM) Ultrasonic machining (USM) is a mechanical material removal process. 6 By 1954, the machine tools, using the ultrasonic principle, had been designed and constructed. This is used in machining of die and tool of drill, wire drawing machine etc. In ultrasonic machining magnetostrictive type transducer is used to generate mechanical vibration. Underwater Welder Salary -How Much They Earn? Operation of the equipment is quite safe. If you found this post helpful then please share it with your friends. Ultrasonic Machining. Now this process is used in many industries to remove metal due to its lower cost, no heat generation, and effective machining. Machining glass, ceramic, tungsten and other hard carbide, gemstones such as synthetic ruby. Used in fabrication of silicon nitrite turbine blade. Typical grain sizes of the abrasive … Ultrasonic Machining Application: The following of Ultrasonic Machining application are: Machining of non-conductive ceramics. The depth of cylindrical holes is presently limited to 2.5 times the diameter of the tool. More the NTD more the size and depth of the cut. This mechanical vibration passes through booster. Different Metals Used in Automobile Engine, Abrasive Jet Machining: Principle, Working, Equipment’s, Application, Advantages and Disadvantages, Drum Brake: One of the Common Braking System. Now we know about basic part and idea of ultrasonic machining. Fresh abrasives cut better and the slurry, therefore, be replaced periodically. 1. This leads indentation of abrasive particle to brittle work piece and removes metal from the contact surface. For drilling holes in wire drawing dies. Experience unprecedented machining efficiency with high performance ultrasonic milling, grinding, core drilling and lightweighting of optical glasses and ceramics. Ultrasonic machining is non-traditional machining process which is used to machine brittle and hard material. A slurry delivery and return mechanism is also used in USM. The electronic oscillator and amplifier, also known as the generator, converts the available electrical energy of low frequency to high-frequency power of the order of 20 kHz which is supplied to the transducer. It is used to erode material in the form of fine holes and cavities in hard or brittle workpiece through the use of formed tools, vibrations of high frequency along with the … The basic structure of a general rotary ultrasonic machining system (RUMS) is shown in Figure 2. The proposed study sheds light on the application of Buckingham approach to model the main effects of these variables on material removal rate in ultrasonic machining of titanium and its alloys. 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. Ultrasonic machining process (USM) 1. 4. The maximum metal removal rate is 3 mm®/s and the power consumption is high. Ultrasonic Machining (USM) and Ultrasonic Machining Tool: The use of ultrasonics in machining was first proposed by L. Balamuth in 1945. If you like this article, don’t forget to share it on your social networks. A minimum corner radius of 0.10 mm is possible to finish machining. Boron is the most expensive abrasive material and is best suited to the cutting of tungsten carbide, tool steel, and gems. Recently a new development in ultrasonic machining has taken place in which a tool impregnated with diamond dust is used and no slurry is used. Read also: Types of Unconventional Machining Process [Manufacturing]. A water based slurry of abrasive particle used as abrasive slurry in ultrasonic machining. For instance, the hole dimensions can be kept within +0.125 mm. The tool has the same shape as the cavity to be machined.

The range of obtainable shapes can be increased by moving the workpiece during cutting. Magne-trostriction’ means a change in the dimension occurring in ferromagnetic materials subject to an alternating magnetic field. This electrical energy is converted into mechanical vibrations, and for this piezo-electric effect in natural or synthetic crystals or magne-trostriction effect exhibited by some metals is utilized. The fine abrasive grains are mixed with water to form a slurrythat is distributed across the part and the tip of the tool. It does not form chips of significant size. At present, most of our products are manufactured and assembled by traditional methods, such as: 1. This abrasive particle strikes to the work piece and remove metal form it. This unit converts low frequency electric voltage (60 Hz) into high frequency electric voltage (20k Hz). Ductile metal cannot be machine by this method. Coarse grades are good for roughing, whereas finer grades, say 1000 grit, are employed for finishing. aluminum oxide (alumina), boron carbide, silicon carbide, and diamond dust. The tool used in ultrasonic machining should be such that indentation by abrasive particle, does not leads to brittle fracture of it. The high-frequency power supply activates the stack of the magnetostrictive material which produces longitudinal vibratory motion of the tool. Your email address will not be published.
