  1. It always seems that engineering and tool design can slide their dates but then manufacturing has to make it up.

    Do you move your part or Make a new WCS?

    I guess it depends on how your shop is set up. Most places I have been, if you move the part out of aircraft coordinates, you can screw things up for the tool designers and others. I guess if you're at a small shop and do everything yourself is doesn't matter. It's kind of funny; when I started programming we used APT-AC. No 3D models. We always moved the part. Once we started using Catia and incorporating 3 dimensional pre-assembly we had to change our ways.

    In aerospace I never move the part. They are created in the aircraft coordinate system. Moving can really screw things up down the road.

    What kind of tool path are you using?
  5. I've programmed Makino and Nigata as well with good results, though Makino is my favorite.

    Machine crash with Vericut?

    I worked at a place that had a guy that all he did was run machine simulation with Vericut. They had spent a lot of time and money to get everything right and used this instead of tape proving on the machine. We ran almost exclusively high speed Makinos. He would get the program after you had finished and ran Vericut yourself. In this instance, that worked great.

    Need some programing help

    My guess would be, he found a solution or discovered a flaw in his question.
  8. It's fine to do cost benefit analysis and all that but, I wish I would have finished my degree just for the accomplishment. I say get your degree, whatever it is; go as high as you can. Some of the highest paid engineers I know are the ones who do stress analysis, at least in aerospace.

    Thanks Steve.

    I've been working with composites, so it's been a while since I've done high speed machining. What kind of sfm do you all use? We're running a VF3 and a VF6. They use IMCO M203N High Performance Streaker End Mills. Thanks

  12. Don't you have to be careful with Ti to not take too light of a cut? Maybe that's old school now. We use to make sure we had enough of a chip load so we weren't just rubbing. Also, if you have a cutter with a specific geometry you have to use a deep enough DOC so the geometry can fully engage and do its' job properly
  13. It's been a while since I've used these and I don't remember how thick to make them. The ones I have here are .015 thick. I was thinking about reducing them to .01. What do you think?
  14. Would this be something like what you are looking for? onsrud
