    3003-H14 Speeds & feeds

    We have a few parts that we need to make out of 3003-H14 aluminum. I haven't worked with this stuff since the 70s, but I kinda recall it being a bit gummy. The parts are 1/8" sheet, can anyone give me speed & feed recommendations for both drilling & milling? We'll be using a 18K spindle router to make them. TIA Zeke

    Yes, the rotations. But the origin points are not synced to the WCS.

    Learning How To Program an Impeller?

    Thanks for linking that video! That is showing a 3+2 using standard 2D paths so the Tool and Construction planes should matter to get the toolpath parallel to the solid face they are machining.

    Move in ARC

    Couldn't this be done by drilling a single hole and creating a Transform-rotate operation?
  9. Using the previously attached part file that function returns the arc direction of the upper profile as CCW when chained clockwise with the C-plane set to TOP; so I think somethings up. I'm using 2020, but I don't think that would make a difference. The below function matches the analyze contour results in my tests. void GetChainDirection() { LPCTSTR prompt(_T("Select a Chain")); CHAIN* selectedChain = nullptr; auto result = chain_1(prompt, &selectedChain); if (result == CHAIN_OK && &selectedChain != nullptr) { auto selectedChainPointer = selectedChain->start; while (selectedChainPointer != nullptr) { auto entityPointer = selectedChainPointer->e_ptr->eptr; if (entityPointer->id == A_ID) { p_3d arcStartVector; p_3d arcEndVector; p_3d crossProduct; p_3d arcStart; p_3d arcCenter; p_3d arcEnd; double arcSweep; view_to_world(entityPointer->u.ar.c, entityPointer->u.ar.view, arcCenter); view_to_view(entityPointer->u.ar.ep1, 1, CONSTR_VIEW_N, arcStart); view_to_view(arcCenter, 1, CONSTR_VIEW_N, arcCenter); view_to_view(entityPointer->u.ar.ep2, 1, CONSTR_VIEW_N, arcEnd); if (selectedChainPointer->ep_n) { arcStartVector = arcEnd - arcCenter; arcEndVector = arcStart - arcCenter; } else { arcStartVector = arcStart - arcCenter; arcEndVector = arcEnd - arcCenter; } crossProduct = Cross(arcStartVector, arcEndVector).NormalizeThis(); arcSweep = std::abs(entityPointer->u.ar.sw) * (180.0 / PI); arcSweep = (int)(arcSweep * 1000.0) / 1000.0; if (crossProduct[Z] < 0.0) { if (arcSweep <= 180.0) { ::MessageBox(get_MainFrame()->GetSafeHwnd(), _T("CW ARC FOUND!"), _T("ArcDirection"), MB_OK); } else { ::MessageBox(get_MainFrame()->GetSafeHwnd(), _T("CCW ARC FOUND!"), _T("ArcDirection"), MB_OK); } } else if (crossProduct[Z] > 0.0) { if (arcSweep >= 180.0) { ::MessageBox(get_MainFrame()->GetSafeHwnd(), _T("CW ARC FOUND!"), _T("ArcDirection"), MB_OK); } else { ::MessageBox(get_MainFrame()->GetSafeHwnd(), _T("CCW ARC FOUND!"), _T("ArcDirection"), MB_OK); } } else { ::MessageBox(get_MainFrame()->GetSafeHwnd(), _T("crossProduct = 0; arc direction could not be obtained."), _T("ArcDirection"), MB_OK); } } selectedChainPointer = selectedChainPointer->next; } free_chain(&selectedChain); } }

    Learning How To Program an Impeller?

    I'm interest in this as well. I was taught that all of my tool planes had to have the same origin as my WCS plane, but watching this yesterday got me wondering if the tool & construction plane's origin positions matter at all.

    Verisurf CMM Reviews Needed ( unbiased preferred )

    I've used PC-Dmis at a previous shop and we use Verisurf at my current shop, as well as the last shop I was at. Verisurf is, hands down, a much superior product. And, as Ron mentioned, it is integrated into Mastercam as well.

    Ron do the Tool and Construction planes matter with 5 axis programming?

    Learning How To Program an Impeller?

    Awesome Ron! I can't begin to thank you enough for this. I can guaranty I'll be using what I learn from this often. We don't make impellers, but the paths and settings here I can use in many other applications. Kudos to you sir.
  15. Today and yesterday I’ve been unable to check out a Mill3D license. I’m able to open MC, but no access to toolpaths. I assumed this was a shortage of licenses, however a coworker was able to check out a license just fine AFTER this. When he opens NHaspX on his PC, it shows 4 active, 1 available. My pc shows 5 active 0 available. What am I doing wrong? Is there a way to see which users have a license checked out?

    help with a VERY deep pocket

    drilling the corners wont work because its a flatbottom and .125 rad corners doesn't leave much left in a .438 square. leaves just a stalk in the center which would be just as much of a nightmare. we tried dynamic but even .0005 or less it would scream. the pocket is +- .01 but its really just - .01 because its right against a wall and cannot go bigger. sending them out for edm is out of the question right now.

    John thanks and in all reality the walls of this impeller would be better machined using a ball endmill and surface machining down the wall. A different way to approach it is do the fin all the way around with one motion verse one wall then the opposite wall. I setup the machine sim using one of the generic machines for those who want to watch the motion, should take the settings and hit the run button in machine sim and go with no issues.

    VERISURF TOOLS for 2020

    Ron, Not sure why you are the only one reporting this install problem. I updated the installer program and made a new build today for you to try. hoping that the newer installer handles any needed Windows updates. So download the latest and give that a try. Thanks Ernie

    Okay took a little bit of work and I didn't use the new Swarf I reverted back to the old school swarf. I also used the Verisurf Tool to convert the Swarf splines into new splines that are constant nodes of 200 nodes. I used Nodes as the Sync process in the chains for the Swarf toolpaths. I also added Transform Operations to help those that struggle with them and how to machine a part effectively using them. File is about 60mb. 5th Axis Impeller in Mastercam 2020 Hopefully this will be a help to others and it is Mastercam 2020. No I will not convert it backwards to a previous version. If I can stay current then your company should be able to also.

    Then look to a dynamic process using the full flute of the endmill using a very small stpe over and slow speed and feed. Maybe 1000 rpm and .0005 to .001 per tooth feed rate stepping in .005 per pass. You said there is a .4 hole thru on the next part try drilling out the corners 1st then coming back and putting in the .400 hole is possible. Might be work hardening the material with the .400 hole. I suspect your going to have to have this Plunge EDM if the tolerance tight. Let me guess it was quoted to be done in 30 seconds and one endmill was going to last 1 million parts and the management is wondering why you can't make that happen?

    Verisurf CMM Reviews Needed ( unbiased preferred )

    What kind of other devices are you looking to support? Does you have Portable CMM along with Fixed CMM? I was the Product Manager for the Master3Dgage years ago when I worked for Verisruf so I am a little biased in saying it is a great product and for any shop using Mastercam to me it is a no brainier. MBD and DPD are fully support with the Moldplus add-on if your looking to do D6-51991 Boeing work. Per the Spec 3. Product Acceptance Software (PAS) Validation is already built into the Verisurf product. They have a great staff that will come in and train your people. Don't let you company only train one person have them train no less that three people if they get onsite training. Target points to the model is probably one of the easiest things you can do with Verisurf to align your models to the CMM. IF you're company is getting Datum Targets points in the MBD then Verisurf can take that data an import it using the CATIA translator and then create an routine for a lot of features directly from that. The AS9100 form is built in the reporting and making Automate measurements plans is very slick. Sorry I know you said unbiased preferred, but I have no issue telling any customer we work with to purchase Verisurf.

    I tried that ….it walked all over the place.the square hole looked like gumbys head! we had great success on the setup pc which was aluminum.

    Move in ARC

    Then yes that is incorrect and would have to use one of the suggestions noted above. Why it has to travel in arc I assume to to avoid the center piece. I have done what others have suggested and drilling one hole then use 2D with no comp to follow the arc from one hole to the next.
