  1. I'd assume (and you know what they say about that..) that NPlus is probably a nACRo or nACo, which from my understanding is basically a nano version of the AlCrN coating. I know that it is harder (as in, cuts & wears better) than traditional AlCrN, but I don't have any real data to back that up.
  2. I put this on in less than 5 minutes, but I have a LITTLE BIT of seat time on Unified :) If you're still on 2021 or 2020, you can use Morph set to Curves for the same effect. if you get weird/inconsistent gaps, under advanced parameters set it to "exact." I just chained the bottom of the fillet and the top of the wall (under the undercut) w/ a 6° tapered 6MM ball mill: Tool axis control is set to rotate around the Z, but keep the tool 87° off of the surface normal so it will sort of swarf, but then I turned on collision control to have it automatically tilt if it'll gouge, so it's not really "tied" to the surface if it has to jiggle to get around those weird bumps. It would be equally easy (but more time consuming for selection) to have done the whole thing, but I wanted to keep the file size down and get you going. Feel free to reach out if you need more help! 1736119534_10333228_A_1-INNERMIDDLEHOUSING_ROUGH_STEP.zip
  3. I regret that I have but one "like" to give....
  4. OOOoffffff, yeah... For sure... I rescind the swarf recommendation. That's not a surface you can (physically) swarf. there's undercuts and twists around all of those bumps and the edges. From the original pictures, I thought it was a straight wall with a bump popping out, but that's not the case at all. I'd use a unified set to either Morph or Guide, and mill between the top and bottom.
  5. Hah, I was thinking the opposite, that those bumps and such are features that you wanted to hit! E.g., when you got to them, "spin" around the top point to create the "cone" bump. If not, use Swarf Milling, and set the collision control to allow gouges within your allowed range, that should smooth those out for you.
  6. Have you tried swarf milling? If that doesn't work, you can try using Pocketing > Wall Finish.
  7. As an extension of that, in the lower-left corner of the tool window, it says "Outlined: Mastercam tool. Rendered: Imported Tool." What that's telling you is that the blue tool is what it recognizes as the profile you want to see backplotting & verifying, however, in the background, toolpaths are still going to calculate it based on the tool geometry Mastercam is using (in this case, a square end mill). If you use this tool on a Contour or Dynamic toolpath, the toolpath algorithm is going to calculate as if it were a 1" endmill. If you were using this to, say, deburr with the Contour toolpath, it would be up to you to figure out exactly how much to shift it left/right/up/down. You can get much closer to the "real" tool shape by choosing the appropriate tool type (in this case, a lollipop), and then using your level to get the backplot & verify geometry perfect.
  8. Agreed. The problem with the tapered ball mills is that often blades are designed for a specific cord contact line, and the larger diameter at the top of the taper often throws that off. I'd be happy to take a look as well, but in general that's why the Swarf Milling toolpath allows you a tolerance to violate/leave material to the points Ron brings up above.
  9. What I've always told people is that on a 5 axis toolpath, I have 50% confidence it'll run right on the machine from backplot, 75% from Machsim without being tied to your post, and 95% with it being tied to your post. To get 100% you need to have a trusted verification software like Camplete/Vericut/NCsimul/etc. What JParis is trying to say is that you have two sets of code being run here. Mastercam toolpaths are stored in a "generic" format called NCI. When you hit the Post button, it runs through your machine's post processor that contains all the information it needs to say "Your machine has a B axis rotating head, so I'm going to adjust the X & Z every time the B angle changes," etc. It's then converted this way into the G code you produce. In order for MachSim to translate any sort of movement, it also has to have its own post processor (called Multi-X post). The problem is that, depending on your machine, your post and MultiX post may arrive at completely different solutions to solve the position; E.g., Machsim goes to A+90, which clears the fixture. Your post chooses to rotate to A-270 which will not clear the fixture. You have no way of knowing that it did that until you run it on your real machine! There's an option available from post builders like Postability and In-House Solutions that hook up the Machisim model to your post, so instead of using the Multi-X post, it uses your post to resolve all of the positions. It won't help with custom M codes and such, but at least all of your positions will be the same as they post out.
  10. Absolutely, there's a lot of great uses of blend. Especially once you understand how the old-school 2d projection mode works, you can really create some nice patterns for stuff that you need some overlaps like combustion chambers. But in this case where you're projecting downwards on a large solid going vertical, there's going to be a few things working against you in tolerance and plane. That's why I suggested switching using the edges of the solid, then you get nice clean edges. I don't have 2021, so I can't save your file back, but it does work nicely if you do it the way I described.
  11. The blend toolpath has to project to your geometry, so you'll often pick up some noise, especially if you're projecting flat curves onto a surface that tapers up to vertical like you're doing. I'd recommend changing your chains to drive directly off of the geometry, and then use avoidance to trim it back as you're trying to do with the chains. So that would mean the top of the fillet and outer edge of the solid, then use avoidance geometry to avoid the center boss by however much you wanted, I think you had .005" or so in your offset chain.
  12. I'm totally biased, but I'm agreeing with Ron.. The 5 axis toolpaths make this stuff so much easier, I wouldn't even mess with the old skool stuff (sorry Pete! :)).
  13. I think you've stumbled across a bug. If you're in "Verify" mode (Home > verify), then the buttons that AHarrison1 showed will do the trick View > Focus. However, in Simulation mode (which is really a lighter-weight version of the full blown "Machine simulation" on the Mastercam > Machine tab), it's not hooked up. In full-blown machine sim, it's controlled by the Simulation > Machine/Workpiece Stock/Tool selection. My guess is that no one has ever tried it when you're in Verify's Simulate mode.... Normally you're doing that to see the kinematics of the machine, so you're not trying to have the machine move around tool, you're trying to see what it's going to do "in real life."
  14. I can't say I've seen anything new with 2022. I deal with step files from various people almost every day. What software are they coming from? Can you post a sample?
  15. Not for the past, say, 10 years? I believe until X7(?), Mastercam used the old verify engine which used to run in the graphics window. As a 5 axis guy all of my life, I was only able to use it 2 or 3 times from the version I started in (V9). It barely worked for multiaxis paths, constant crashes and took forever to verify. It was faster to run on the machine!
