Laser Beam Machining: Definition, Parts, Working Principle, Advantages, Application

Image
  Laser Beam Machining: Definition, Parts, Working Principle, Advantages, Application Laser Beam Machining (LBM) is a form of machining process in which laser beam is used for the machining of metallic and non-metallic materials.  In this process, a laser beam of high energy is made to strike on the workpiece, the thermal energy of the laser gets transferred to the surface of the workpiece. The heat so produced at the surface heats, melts and vaporizes the materials from the workpiece. Light amplification by stimulated emission of radiation is called LASER. Laser Beam Machining Construction or Parts: Laser Beam Machining consists of following main parts: 1. Power Supply 2. Capacitor 3. Flash Lamps 4. Reflecting Mirror 5. Laser Light Beam 6. Ruby Crystal 7. Lens 8. Workpiece 1. Power Supply: The electric current or power is supplied to the system. A high voltage power system is used in laser beam machining. It will give initial power to the system after that reaction starts in a laser t

Water Jet Machining: Definition, Parts, Working Principle, Advantages, Application

Image
  Water Jet Machining: Definition, Parts, Working Principle, Advantages, Application 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. In order to cut harder materials like metals or granite, an abrasive material is mixed in the water. Water Jet Machining Construction or Parts: Water Jet Machining Consists of following Various Parts: 1. Reservoir 2. Hydraulic Pump 3. Hydraulic Intensifier 4. Accumulator 5. Control Valve 6. Flow Regulator or Valve 7. Nozzle 8. High Pressure Tubes 9. Drain and Catcher System 1. Reservoir: The reservoir is used to store water which will be used as a jet. From the reservoir, the water is supplied for the water jet machining process. 2. Hydraulic Pump: In the water jet machining process, a hydraulic pump is used to pump the water from storage tan

Abrasive Water Jet Machining: Definition, Parts, Working Principle, Advantages, Application

Image
  Abrasive Water Jet Machining: Definition, Parts, Working Principle, Advantages, Application Abrasive-Water Jet Machining (AWJM) is a non-traditional machining process or advance water jet machining process in which abrasive used as a medium. To overcome the disadvantage of water jet machining, the abrasive particles will be added into the water so that the abrasive particles along with water also come out from the nozzle at a very high velocity to remove the material from the surface of a workpiece to get desired shape and size at high accuracy. Or When an abrasive material is used in the water for the machining process then it is called Abrasive Water Jet Machining (AWJM). PARTS OF AWJM:- 1. Reservoir: The reservoir is used to store water which will be used as a jet. From the reservoir, the water is supplied for the abrasive-water jet machining process. 2. Hydraulic Pump- The hydraulic pump is generally used to pump the fluid from one place to another place whereas here in this unit

Abrasive Jet Machining: Definition, Parts, Working Principle, Advantages, Application

Image
  Abrasive Jet Machining: Definition, Parts, Working Principle, Advantages, Application Abrasive Jet Machining is a material removal process with the help of concentrated abrasive grains enclosed in a nozzle that removes by the action of impact erosion. In abrasive-jet machining, a high-velocity jet containing abrasive particles is aimed at the workpiece surface under controlled conditions. The impact of the particles develops a sufficiently concentrated force to perform operations such as cutting, the material is removed by the erosion of work material with abrasive grits at a speed of 150-300m/s. The abrasive grits are carried out in a high velocity gas stream. Abrasive Jet Machining Construction or Parts: Abrasive Jet Machining Consists of following Various Parts: 1. Gas Supply 2. Filter 3. Pressure Gauge 4. Mixing Chamber 5. Nozzle 6. Abrasive 1. Gas Supply: A high-velocity jet of air like nitrogen carbon dioxide etc. and enclosed abrasive particles is aimed at the workpiece under

Conventional & Unconventional Machining Process

  Conventional & Unconventional Machining Process Conventional Machining  Process: - The conventional machining process is a process in which a human operator operates the machine manually by hand such as lathe machine, drilling machine, milling machine, slotting machine, shaper machine, planer machine, etc. This machining process is also called as traditional machining process .  Unconventional Machining  Process: - The unconventional machining process is a process that uses less human effort, usually a fully automated machining process. Such as abrasive jet machining, water jet machining, ultrasonic machining, etc. This machining process is also called a non-traditional or non- conventional machining process.  Conventional Machining Process Unconventional Machining Process Example of the conventional machining process is lathe machine, drilling machine, milling machine, etc.   Examples of the unconventional machining process

DESTRUCTIVE AND NON-DESTRUCTIVE TESTING

 DESTRUCTIVE AND NON-DESTRUCTIVE TESTING Testing is the physical performance of the operations to determine the qualitative measure to certain properties such as mechanical. Testing aims to determine the quality. Types of Testing- There are two types of testing 1. Destructive Testing 2. Non-Destructive Testing 1. Destructive Testing The destructive testing is the testing in which test piece or specimen is destroyed during the test. After testing the specimen remain no longer to useful for further use. The following destructive test are- a. Tensile testing (TT) b. Bend testing (BT) c. Impact testing (IT) d. Nick-break testing (NBT) e. Hardness testing (HT) f. Etch testing (ET) 2. Non-Destructive Testing The Non-destructive testing is the testing in which test piece or specimen is not destroyed during the test. After testing the specimen is useful for further use. The following non-destructive test are- a. Visual testing (VT) b. Stethoscopic test (ST) c. X-Ray & Gama Ray test d

ADDITIVE MANUFACTURING PROCESS STEPS

Image
AM PROCESS STEPS Additive Manufacturing involves a number of steps that move from the virtual CAD (Computer Aided Design) description to the physical resultant part. Different products will involve Additive Manufacturing in different ways and to different degrees. Small, relatively simple products may only make use of Additive Manufacturing for visualization models, while larger, more complex products with greater engineering content may involve Additive Manufacturing during numerous stages and iterations throughout the development process. All the Additive manufacturing processes have the following eight common steps- Step 1- 3D model creation Step 2- STL file creation Step 3- STL file transfer Step 4- Machine set up Step 5- Build Step 6- Part removal Step 7- Post processing Step 8- Applications Step 1- 3D model creation All Additive Manufacturing parts must start from a software model that fully describes the external geometry. This can involve the use of almost any CAD solid modelin
