    Verify movement

    We had a problem with drills and taps "doglegging" into a wall with #1401.1 =1. Fanuc stated that there is still a small amount of doglegging going on and the only way to fix it is to use G1 for every movement. I ended up doing full retracts between the three holes since this was the only part we have had an issue with. I think that part is obsolete now.
  2. I could see speeding up the feed as a possible issue for probe stylus breakage but unpredictable motion seems odd.

    Machining inclined groove with T slot

    If you don't have a 5 axis and the groove bottom is flat you can use a sine vise on top of a sine plate but the top walls will need to be surfaced with an undercutting type cutter.
  7. We have a part made from Noryl™ that needs a "customer visible" finish or what would be a very nice finish with Delrin™ (previously what we used) on the OD of the material. The material is around Ø6.00 and the diameter tolerance is loose. I'm thinking we need a dead sharp uncoated insert that can handle abrasive material but I could be completely wrong. Can anyone give me insert recommendations? TIA
  8. I don't know what our "packages" are but our Fanuc and Mitsubishi probing are the same on the programming side.
  9. What documentation are you looking through? I'm at home but the documentation we have shows the program numbers and variable numbers used and how to use them.

    Royal quick grip collet chuck

    We have them on our two 4-axis lathes. They work very well.
  12. Award cutter is about a mile away from Conical tool and is less costly than Conical. They both have the same quality.

    Will more ram speed up toolpath nesting?

    Are you nesting the same part or an assembly of parts? If they're the same part or multiple different parts you may be able to use subprograms to lessen the crunch time.
  14. Is the part to be aligned a purchased part? If not, you can machine the holes and slot on the lathe.
  15. Try creating your own end mill with the radius you want .dxf style.
