5. Design Considerations: Capabilities Cutting Drilling Five-axis Processing Surface Texturing

6. Design Considerations: Material Applications Water Only: Foam Rubber Plastics Abrasive: Metals Exotic Materials Composites

7. Design Considerations: Applications

8. 20 min – Includes Setup & Cleanup Time.5” hastalloy +/-.002” Tolerance

9. Design Considerations: Edge Finish Edges have a sandblasted appearance Harder materials exhibit better edge finish Finishes will range from 63 RMS to very coarse depending upon the application Eliminates grinding and polishing, reducing secondary operations costs

10. Design Considerations: Why use Water Jetcutting? Eliminates pre-drilling Narrow kerf allows tight nesting Cuts all types of materials Accurate cutting of soft materials Cuts thick materials Titanium – 15” Inconel – 12”

11. Advantages/Disadvantages Advantages: Cuts all materials No part distortion No heat affected zone Cut intricate shapes Tight tolerances Easily programmed Non-toxic Disadvantages Start-up Cost Noise Pump Maintenance Water Filtration Slow Cutting Rates
