Diamond turning is an essential manufacturing process used in direct machining of optical surfaces in many areas of photonics. A few examples include: infrared optics (both commercial and defense), plastic injection mold inserts, and mirrors (spectrometers, telescopes, satellite, etc.).

This tutorial will cover the following topics:

  • History of machine tools on the way to ultra-precision
  • Enabling machine tool technologies
  • Machine configurations
    • 2-axis turning, slow and fast tool servo, flycutting and milling
    • Machine errors
    • Machine tool companies
  • Diamond tool basics
    • Single crystal and polycrystalline
    • Geometry
    • Suppliers
  • Diamond Turning materials
    • Metals (D-shell electron phenomena)
    • Brittle materials: Crystals, IR glasses, ceramics
  • Machining parameters
    • Feed rates, depth of cuts, spindle speeds
    • Typical roughing and finishing
