    help with a VERY deep pocket

    If you are determined to do this without and EDM I would drill it and flat bottom drill it to within 0.01" of the bottom (about 10mm dia). Then go in with the biggest end mill and pocket it and keep stepping down with your end mill sizes (3/8", 5/16" etc). When you get to the 1/4" long end mill set your stepovers to 0.001". You will need to really look at the backplot carefully to check the overlap. It is in the corners that it will engage more material.

    2020, Simulator Problems

    There is the Sync Simulator to Mastercam option. I personally think is is terrible, but you may like it.
  5. Can you share the file if not email me and I will be glad to see what I can do if I can confirm you a legal user of the software. I personally paid for my seat and how I feed my family so if your not a legal user the help stops here.

    Leave .01 on the floor then come back with the endmill. Have you thought about a keyseat cutter?

    Punch out a bigger hole and press/weld/thread in a plug with machined features?

    2020, Simulator Problems

    Thanks, Ron, I have the latest RTX4000 drivers...also, working from home with the Company's computer via VPN. It would freeze on Startup and although I can Click through the Menu button, the Toolpath did not move. If you tried to close it, I would get Server Busy Message, but could not Switch To..., nor Retry. I had to go to the Task Manager and End Session for MasterCam. I can only think it is the STL file … so I started over … Ran Operation 1 on a fresh Solid in MCAM and then saved the STL (RUFF-A.stl). Operation 2 uses that STL as a Stock Model. I then Prove out the 2nd Operation and save that STL (RUFF-B.stl). It would freeze using RUFF-A.stl. But, I think re-making my STLs over, everything seems to work. It there a way that using a Created WCS, the Simulator viewports would use the same view as MCAM as it did in the Past Versions? For example, I would be in an isometric view of my WCS, but the simulator would be in the World WCS Isometric view with the Focus Icon selected to Workpiece. I changed it to Multiple Workpiece and it works. Is this what is expected? Don Dawson Corona, CA

    I cant have all of that folded over crap at the bottom.we rotary broach too.

    I'm using the Slater Tools system & broach....they were extremely helpful. Working on a Mazak HCN-4000
  12. AGREED! Lathe with Mill Ive just been figuring it out as I go from past mastercam files of the company im with but even looking back at them my planes are all matching up like they had them for the very same type of operations. I wonder if it has something to do with my model's orientation to my plane. But it shouldn't right cz that C Axis has 360 degrees of travel. I dont know man. If you dont think you can walk me thru it no worries ill figure it out eventually. thanks!
  13. You need some training on the planes and process. Are you MT or Lathe with Mill?
  14. the right plane facing the check? i dont know what that means lol im sorry man. Im using my Top Plane as my WCS and Cross Upper Left [Top] Plane as my Tool Plane and Construction Plane. Same as i am in my milling toolpath which works fine. But for this chamfering tool path it doesnt wanna work right.

    I was thinking of something along the same lines. Thanks for letting us know that is working for you.
  16. Should be able to just call the Right Plane is facing the check. If facing the center line along the X axis then should be able to call TOP, FRONT, BACK or BOTTOM.
  17. I'm programming for a Mori Seiki SL-25Y. Im milling a big chunk out of a 304 SS tube. I've already completed the milling operation with an end mill. Now I want to chamfer my milled edges with a 45 deg chamfer mill and mastercam keeps flipping my tool or my part orientation upside down?! Im using the same plane as I did for the end mill ( Cross Upper Left [Top] ) and my part is oriented the same and I'm using the same tool path ( C axis Cross Contour) Hopefully someone out there has more experience with this than me cuz i am stuck. lol

    help with a VERY deep pocket

    If you have very deep pockets, buy a few Yasda's. Then they won't be deep anymore....

    I'm currently Rotary Broaching a .313 hex x 1" deep in Aluminum...that's pushing the length to dia ratio for that process....

    One other possibility is using a series of rotary broaches to finish it but that is really deep. https://www.polygonsolutions.com/how-rotary-broaching-works/

    help with a VERY deep pocket

    On a similar part (but nowhere near as nightmarish), I've drilled the center, then used the Contour toolpath set to Oscillate with small High Speed bump at the bottom. It helped dampen the harmonics/deflection of just doing the cut normally. Then you do another contour and offset the start point by half of the High Speed distance and a smaller depth to clean up most of the material. Kinding giving the benefits of plunge cutting without just he vertical chatter issues. Another trick I saw once (but I've never done!) was to use a single-point tool holder and shim the tool above/behind the tool so that the tool was intentionally out of round by the amount of deflection. But if you can't get a tool holder down there to have less than an inch of stickout, that isn't going to help you. But yeah, to answer the question properly, EDM

    Make sure you are using the latest Video Card drivers for your computer.

    Sounds like you doing the impossible so just keep doing what you can to make the impossbile happen is all I can say.

    3003-H14 Speeds & feeds

    Sharp tools and if you have an oil mister use it. 2000 to 4000 sfm would be my starting point. 2 Flute or maybe even a single flute tool might be a good option. Pay attention to the chip and the tool and go from there.

    Move in ARC

    I don't think it will create the arc move around the center boss like they want. I have to assume the tool is long and to bring it up and over might over travel the machine. I have done things like this over the years and like others mentioned it just some work.

    Verisurf CMM Reviews Needed ( unbiased preferred )

    This is great info thanks! It's great to hear from real world people. We only have fixed cmm's at this shop but would like to implement new technology when the time is right. Our sister shop has fixed machines and a smart scope for optical measurements. I don't know much about the CMM world but i know enough to see the advantages of great software. We are currently doing D6-51991 work but use other validation software. Thanks for the help!
