  1. I use Mastercam, Haas, and Solid Works to manufacture, repair and model aerospace structures.

  2. Try here: http://www.machinetools.com/us/auctions
  3. Make sure that your drill size is correct, it is different depending on the class and whether it is form or cut tap. It should be 5/64" drill for a form tap or .078"-.080" ,and a #51 drill for a cut tap or .067"-.069".
  4. I am trying to do 5 axis tapping with a tapping collet, a Rego-Fix ET1 with axial compensation. here is the recommendation: Fast approach, then feed the tap with approximatively 95% of the pitch value, which uses 20-30% of the compensation stroke when the spindle rotation and the feed movement are simultaneously reversed. Return feed must be made with 100% of the pitch, which maintains the sleeve of the collet in the compensation stroke up to the tap disengagement. I am using a Haas controller with rigid tapping. Can I do this in Mastercam, or do I need to put the code in manually? OK I got the code, I edited it manually. Now can anyone suggest a good rpm for form tapping a 10-24 blind hole in 6061-T6 without breaking the tap??? I guess I will answer my own questions this time. The manufacturer recommends 50-90 sfm or 1000-1800 rpm for a 10-24 unc with a 25%-50% reduction in blind holes. Thank me! LOL
  5. I use a Hanita 3/4" 3 flute variable pitch at 8400 rpm. 200 ipm .50" doc. I prefer polished uncoated solid carbide to TICN coated in aluminum.
  6. I put everything to the top plane and saved it and now it is in the right posistion, thanks!!
  7. I am currently in the bottom view and everything is set to that view.
  8. I have machined the bottom of a part and now I want to do a stl compare but the stl model is in the wrong position. How can I save it so it is in its' current posistion?
  9. I created a surface in the area I wanted to machine and that solved the problem. I also figured out that if I would have made my containment boundry larger then it would have cleaned up in the first place.
  10. I am trying to make a surface rough parallel operation into a surface finish parallel operation, but everytime I try it gives me a warning invalid arc message and then it deos not generate the toolpath. If I leave it as a rough operation it spends most of the time cutting air.
  11. You can try this company they have done some nice work for me in the past.Northwest Machine works, ask for Nick, http://www.nwmw.com/
  12. So, is that good or bad? P.S. Nice computer you're using, I bet it really smokes!!!
  13. Just wow? Can't you elaborate just a little?
  14. This machine is a gantry and is much larger than a VF and I need to drill and bore or ream some very tight tolerances +/-.0001". I did some drilling with a .390" cobalt taper length drill. I used the mastercam speeds of 130rpm at .2 feed and if I increased the feed it made the rpms jump back and forth more and more. These are very unigue parts, I have to go through .625" thick ti. then aluminum then air then aluminum and then back through .625" of ti. again, a total of 5 inches. There are already holes at .375". I would like to mill them but how can I reach the bottom in such a small diameter?
  15. My boss wants me to machine titanium 6AL-4V annealled on a Haas GR512 that has a 15 hp spindle with 17 ft-lb max torgue @4600 rpm and I just do not think it will work on this machine. It is not rigid enough and does not have enough torgue in my opinion. Does anyone agree with me or not and why? Thanks.
