Ultrasonic Machine: Defination,working principle,parts,types,application,advantage,disadvantage,limitation

Introduction:-

It is a subtractive manufacturing process that removes material from the surface of a part through high frequency,low amplitude vibration of a tool against the material surface in the presence of fine abrasive particles.


  Parts of Ultrasonic Machine:-
  • Power Supply
  • Electro-mechanical transducer
  • Velocity Transformer
  • Tool
  • Abrasive Slurry
  • Abrasive gun
  • Workpiece

Types of ultrasonic machining:-

• Roatary Ultrasonic Vibration Machine
•Chemical assisted Ultrasonic machine


Application of Ultrasonic Machine:-

  • This process is used for drilling both circular and non-circular holes in very hard materials like carbide, ceramics, etc.
  • This process is best suited for brittle materials.
  • The machining operation is simple and requires less time.
  • This process is economical.
  • Glass, Ceramic, tungsten land semi-precious stones can be machined.
  • A semi-skilled operator can operate the machine.
  • Better efficiency can be achieved.
  • Good surface finish.
  • It is suitable for both conducting and non-conducting materials.
  • High accuracy can be achieved.

Advantage of Ultrasonic Machine:-

•This process is used for drilling both circular and non-circular holes in very hard materials like carbide, ceramics, etc.
•This process is best suited for brittle materials.

Introduction:- Electric discharge Machine is the process of metal removal from the work surface due to an erosion of metal caused by electric Spark discharge between the two electrode tool and the work piece. Electrical Discharge Machining is also called or known as Spark machining, spark eroding, burning, die sinking, wire burning or wire erosion. This spark near to 8000 to 12000ยบ C. Parts of Electrical Discharge Machine :- • DC Power supply   •Voltmeter •Ammeter •Tool •Die-electric fluid •Pump •Filter •Servo- controlled feed •Fixture •Table Working of Electrical Discharge Machine :- It consists of an electric power supply, the dielectric medium, the tool, workpiece, and servo control. The workpiece is connected to the positive terminal and the tool is connected to a negative terminal of the DC power supply. An air gap of 0.005 to 0.05 mm is maintained between the tool and the work. The die electric fluid which is non-conductor of electricity is...

Abrasive Jet Machine: Introduction, Working principle, working process,parts, Application, Advantage, disadvantage, diagram with suitable name

Image
Introduction:-   It is the process of impinging the high speed stream of abrasive particles by high pressure gas or air on the work surface through a nozzle and metal removal occurrs due to erosion caused by high speed abrasive particles.       In this Machining,the abrasive particle size is 10-40 micros.      Jet velocity will be 150 to 300 m|sec. And it is used to superalloys. Parts of Abrasive Jet Machine:- 1.  Gas supply 2. Filter 3. Pressure gauge 4. Regulator 5. Mixing chamber 6 . Nozzle Working Principle of Abrasive Jet Machine:- The figure shown is the above Abrasive jet Machining. It consists of a mixing chamber, gas filter, pressure gauge, regulator, and the nozzle. The filtered gas at a pressure of 2 to 8 kgf/cm2 is supplied to the mixing chamber containing the abrasive powder and vibrating at 50 Hz, where it mixes with abrasive particles and then enters into the connecting hose. The abrasive and gas mixture c...
