There are different jet or beam processes, namely Abrasive Jet, Water Jet etc. Laser beam machining (LBM) is a machining method primarily used for hard metals or those that would be impossible to machine with traditional techniques. This process is experimental and the keywords may be updated as the learning algorithm improves. If you continue browsing the site, you agree to the use of cookies on this website. Thus these two processes are often classified as electro-optical-thermal processes. Create an account or sign in to download this. This parameter is key in determining the fusion zone profile (area of base metal melted) on a workpiece. Presentation Summary : This machine uses a laser that burns through the material. 1. This process uses thermal energy to remove material from metallic or nonmetallic surfaces. Uses a power generator (FS laser, Excimer laser) that emits a beam with very high measure energy. The heat energy contained by the laser beam gets transferred to the surface of the w/p. Laser beam machining (english)! Do you have PowerPoint slides to share? In the Electron Beam Machining process, a high velocity focused beam of electrons are used to remove the metal from the workpiece. Beam Machining (EBM) and high-energy coherent photons in case of Laser Beam Machining (LBM). History. Laser beam welding is highly efficient and ideally suited for this purpose. Laser processing technology (FIG. In the electrical beam machining, electrical energy is used to generate the electrons with high energy. Laser Beam Machining Working Principle: Looks like you’ve clipped this slide to already. Laser beam machining (LBM) is one amongst the foremost widely used thermal energy based non-contact kind advance machining method which may be applied for nearly whole vary of materials.

Displaying laser beam machining PowerPoint Presentations Electrical Discharge Typically Provides Even Higher Power Density With Smaller Spot PPT Presentation Summary :Electrical discharge typically provides even higher power density with smaller spot size. In this way the machining of material takes place by the use of laser beam.Also Read: 1. From: Micro Fuel Cells, 2009. Some very high power fiber lasers could cut 50 mm. See our User Agreement and Privacy Policy. Laser Beam Machining – Main Parts, Principle, Working with Application; Advantages. Laser beam machining (LBM): Principle of Laser beam machining (LBM): Conversion of electrical energy into heat energy to emit laser beam ; Laser beam is focused over a particular area on workpiece which creates high intensified concentration on work piece because of which the work piece melts, thus giving the required shape. It is used to machine both metallic and non-metallic material. Microstructual Analysis Of Heat Treated EN8 Steel, No public clipboards found for this slide.
