Glass Cutting

  • Scoring
    • Fissures
      • Initiate crack that propagates through the glass
      • Optimum depth depends on glass thickness
    • Wheel Materials
      • Tungsten Carbide
      • Hardened Steel
      • Polycrystalline Diamond
    • Wheel Types
      • V-wheels
      • Structured Wheels
    • Lubricants
  • Mechanical Stress
  • Thermal Shock
  • Laser-based cutting
    • Can be full cut or scribe
    • Work by heating and cooling rapidly
    • Leaves an extremely high quality edge
    • Laser Ablation
      • Allows high-quality holes and internal shapes
    • Laser Filament Cutting
  • Abrasive Water Jet
  • Diamond Dicing
  • Edge Quality
    • Edge Strength
    • Chippings
    • Post Processing
      • Grinding, Polishing
  • Mechanical Testing of Cut Glass
    • 4 Point Bending Test
    • Ring to Ring Test
    • Ball Drop Test
