Tooling

• Preliminary Study
  • CVD Insert in Severely Interrupted Cuts
    • Finish Turning Operation
      • Cutting Parameters
        • 1500 sfpm
        • .050 in. DOC
        • .005 in. ipr
  • Not only did this insert (TPG-322T by SP3 ) not fail catastrophically, it stood up to interrupted cuts.
  • Cost Advantages:

    PCD is in the $100/insert range
    CVD is in the $50/insert range, AND...
    

Notes:

• Diamond Coated Cutting Tools
  • SP3 , Norton
    • Literature boasts of substantial increases in productivity - up to nine times more parts per tool
      • Don’t really know what this means - what parts? What material? Speeds? Feeds? DOC’s?
      • Who did this testing?
    • Preliminary Study was done at IAMS
      • 4.5 in3 per min. material removal rate
      • good surface finish (< 60 uin)
      • stood up to interrupted cuts, so porosity is no longer the issue it was
      • all very preliminary
