This is a set of tests to determine the most efficient way of clearing swarf from Night Vent slots

Sommaire

Test 1.

Baseline, This does a single pass 35mm deep with a 12.7mm tool on the top, then the bottom of the profile

Tool Speed is 25 and the operation took 22 seconds.

  2. Bottom of Profile
  1. Top of Profile

  2. Test 2.
  3. This does a single pass 35mm deep with a 12.7mm tool on the Bottom, then the Top of the profile Tool Speed is 25 and the operation took 22 seconds. there was no appreciable difference from the baseline
  4. Top of Profile
  5. Top of Profile
    Bottom of Profile
  6. Top of Profile

  7. Test 3.
  8. This continues to rout the bottom of the profile first but does so in 2 half depth passes, the tool speed is still 25 and the operation took 36.9 seconds
  9. This has cleared a little of the swarf out but is not much better than the baseline
  10. Top of Profile
  11. Top of Profile
    Bottom of Profile
  12. Top of Profile

  13. Test 4.
  14. With this one, I sent a 5mm slot then the 12.7mm slot over it, hoping that when the 12.7mm slot routed, the centre of it would already be taken out and allow the swarf to fall inwards both these slots were in 2 depth passes, and again I routed the bottom, then the top as speed 25, this operation produced good results, but took a whopping 75 seconds.
  15. Top of Profile
  16. Top of Profile
    Bottom of Profile
  17. Top of Profile

  18. Test 5.
  19. This was the same as Test 3 (bottom then top in half depth passes) but as the tool was not taking out as much profile I moved the tool speed up to 35. this took 28.8 seconds.
  20. Top of Profile
  21. Top of Profile
    Bottom of Profile
  22. Top of Profile

  23. Test 6.
  24. The last test was similar to test 4 (5mm pre rout, half depth passes) but at speed 35, this operation took 57.5 Seconds
  25. Top of Profile
  26. Top of Profile
    Bottom of Profile
  27. Top of Profile

Summary
Test Speed Results
1 22 Seconds Bad
2 22 Seconds Bad
3 36.9 Seconds Moderate
4 75 Seconds Good
5 28.8 Seconds Good
6 57.5 Seconds Good
  1. Conclusion
  2. I was surprised at how much better the results were on test 5 when the tool speed was increased, this was a better prep AND faster. This prep was only 28.8 seconds as opposed to the baseline of 22 seconds. the 5mm pre slot produced good results both times but at 75 seconds with 25 cut speed and 57.5 seconds at 35 cut speed, the operation was far too slow. I believe test 5 to be the
