  1. Laser cutting system • LASER: • Light Amplification by Stimulated Emission of Radiation

  2. Introduction • There are two types of lasers used for cutting: • the gaseous CO2 laser • the solid-state Nd : YAG laser.

  3. Applications • Wood • Paper • Leather • Glass • Ceramic • Metal • Steel, Titanium, Paper, Wax, Plastic, Fabric

  4. Drawbacks • Material limitations (including crystalline and reflective materials) • Producing a piercing hole that can make the pattern design more difficult. • Reflected laser light can present a safety hazard

  5. Economics of Laser Cutters A 1000 – watt laser beam focused to a spot .005 inch in diameter is equal to 5,000,000 watts/square inch Beam Dia.; .005 - .009 inch

  6. Optical Unit • Mirrors direct the beam from the source down to the lens • the lens then focuses the beam into the desired geometry • finally the assist gas is added to remove the molten metal www.cncmachines.us

  7. Laser Surface-Engineering Processes An outline of laser surface-engineering processes. Source: After N. B. Dahotre.

  8. Science • The Beam • .0875-.5 inches from the source • ~.001 inch at the work piece • Many factors are material and thickness dependent • focal length, beam intensity, reed rate, cut with (kerf), cut time, machine configuration • Types of cut • Vaporization cutting, Melt and Blow, Thermal stress cracking, Burning Stabilized

  9. Bio Implant

  10. Laser Surface Texturing

  11. Pace Makers • Utilizes laser cutting, welding, marking.

  12. Applications Few References: George Chryssolouris, J.C Rozzi, Y.C.Shin, B.P.Bandyopadhyay,S.Jahanmir, S.Harimkar, A.Samant, N.Dahotre

  13. Processes and Practices • Current Uses of Laser Cutting Systems • Primarily 2D Systems • Either melts, burns, or vaporizes away material • Used to cut flat-sheet metal and piping/structural materials

  14. Conclusion • There are many useful applications and uses for Laser Cutting in the current manufacturing market • Many new innovations are on their way and new uses for this versatile cutting process are cropping up each year
