Electron Beam and Laser Beam Machining. This course also gives emphasis on cutting fluid emissions and its effect on operators, environment and water pollution.

Introduction to Machining and Machining Fluids

Please click here to learn more. Hybrid processes such as laser-assisted machining have emerged in this industry recently. You can manage your calendar by clicking on the button below. The extremely high requirements for quality of macginability optics leave virtually no room for error.

Manufacturing Processes – II NPTEL by World Mentoring Academy – SpeedyCourse USA

Despite all the automation involved in the diamond turning process, the human operator still plays the main role in achieving the final result.


This site also uses cookies to deliver our services. Basic principle, purpose and application of grinding. Diamond fly cutting can be used to generate diffraction gratings and other linear patterns with appropriately mahinability diamond shapes.

Forces developing and acting in machine tools.

Manufacturing Processes – II NPTEL

The most often requested materials that are not readily machinable are: The granite base is placed on air suspension on a solid foundation, keeping its working surface strictly horizontal. Back to Online Courses. Standoff distance, angle of impingement, contact angle, area of cooling, Solid lubricants.

Introduction to modern machining processes: The diamonds that are used in the process are incredibly strong in the vertical downward direction but very weak in the upward and sideways directions. Introduction to Numerical Control. First Name Last Name. Typically, the part to be npgel is first described using a CAD model, then converted to G-code using a CAM program, and the G-code is then executed by the machine control computer to move the cutting tool.

Even with the relatively high volume of optical components manufactured using the SPDT process, this process cannot be classified as mass production, especially when compared with production of polished optics. Temperature changes of a few degrees during machining can alter the form of the surface machinaiblity to have an effect.


This article needs additional citations for verification. Process Parameters and setups. Get personalized course recommendations, track subjects and courses with reminders, and more.

Send a new code. Tags engineering machines fluids. A diamond-tipped lathe tool is used in mmachinability final stages of the manufacturing process to achieve sub- nanometer level surface finishes and sub- micrometer form accuracies.

Several techniques have been investigated to prevent this reaction, but few have been successful for long diamond machining processes at mass production scales. The cutting tool is moved with sub-micron precision by a combination of electric motors and piezoelectric actuators.

Construction, working principle and applications of shaping, planing and slotting machines. Diamond turning is turning with diamond as the cutting tool. Initial stages of machining are carried out using a series of CNC lathes of increasing accuracy. Plastic optics are frequently molded using diamond turned mold inserts. Tool Geometry, Tool signature.
