Laser Cutting Process Fundamentals

  • Absorption: Material-wavelength interaction determines energy coupling efficiency
  • Heat Conduction: Thermal diffusivity affects heat affected zone size
  • Assist Gas: Oxygen enhances cutting through exothermic reaction
  • Power Density: Must exceed material's vaporization threshold
  • Speed Optimization: Balance between cutting speed and edge quality
