Thanks. I tried flowline and it's leaving a cusp up at the very top. I do see that it takes the stock perpendicular to the surface. It appears that that ends up cutting too much stock away. I need that TSC between the top of the trode and the angle to move .005" in the Y axis. We do circular orbiting in the XY axis for almost all of our jobs. So yes, a .005" radius is left in the corner and that's fine. I've got the waterline path running in the machine right now. I started at -.002 stock and now I've adjusted it to -.004. This is not a critical feature, but I'd like to be able to get it right. And, I'm self-teaching here at work.

I watched "Stock Aware Finish Machining" on lunch. Not quite what I was looking for, but still very useful. Would you be willing to post the link to the video you're referring to?

Thanks for the replies. Is that video called "Stock Aware Finish Machining"?

I have attached a file of an electrode that I'm working on. In the third operation, I go around the bosses with the cutter set to -.005" stock in order to get my .005"/side overburn. My question is about the angled surface that I'm finishing in the fourth operation. When I set a wall stock value like -.005" does Mastercam offset along a machine axis (Y in this case) or normal to the surface? That small flat from sharp corner to sharp corner measures .020 and I need it to be .010 on the carbon. RH 11659-60 electrode.mcam

Yes, that's it, thank you!

I always have the Levels, Planes, and Toolpaths managers docked on the left side of my screen. When I would call up any other function, like creating wireframe, trimming, filling holes, that dialog box would appear over the managers, or the managers would auto-hide. Well, suddenly, any additional dialog box appears right next to the managers, shrinking my screen space. How can I go back to what I had? I'd like to not have to use auto-hide.

I've found an answer. I extended my surfaces above the part. However, is there a way to accomplish what I'm after using strictly toolpath parameters?

Thanks. I found the attachments link and understand it now. Here is the Dropbox link to my file. There is one one op now. https://www.dropbox.com/s/43xb0m977btcplo/runner pin b.mcam?dl=0

Data allotment? What is the maximum amount? This is news to me.

I'm having a problem where Equal Scallop is cutting past a containment region as well as on top of an avoidance region. Hybrid is doing the same thing. I've attached the file. Op 2 is the problem and you can see the witness mark on the top of the part running parallel to the slot. Edit: Forgot to post the file. Max size 71KB? How can I post my file?

And I see that's where you're going in the picture you posted. How did you get that geometry drawn?

I tried Flowline, but it had issues with the changing offset side. I wanted one path to cut down the wall, into the corner radius, flat across the floor, and then coming back up along that 45-deg cone. Hybrid got me there, mostly. There are some junk moves that I can't seem to get rid of. They left some gouges in the corner radius. Again, not critical on this part, but I'd like to be able to control them. I turned on G187 P3 E.001 and cut tolerance/line arc tolerance of 62/38, G17, G18, G19 and one-way filtering. I must have gotten lucky. It fixed the scalloping problem, and the machine ran mostly shudder-free. I went back and rechained the area with surfaces, and it looks cleaner. What do you think? Stepdown and stepover are loosened so I can post the file. locating ring hybrid.mcam

I'd be curious to see your 2D Swept geometry if you can get it uploaded. Is the Across geometry in a section view?

This is a photo of a part I'm working on. All was well until I surfaced the entire pocket area; scalloping on the walls. Now, this is not a critical part, but I'd like to be able to control this. Is this an arc filter/tolerance settings issue? I've attached my file as well, just the toolpath I was using. Thanks. locating ring scallop.mcam I should add that in the file I uploaded, "Create Arcs in XY" is checked. It was NOT checked when I ran the part.

Thank you! That's what I needed.

JParis and AHarrison1, I got both of your methods to work. CrazyMillman, I like that idea, but I'm lost on how to get there. I copied the part to a new level. I know that I can Move the two complete holes, but what about the four that are on the diameter?

On this file, I want the surface in orange to wrap all the way around the part. On level 10, I created 4 surfaces from the solid, created wireframe and then lofted 4 smaller patches, but that doesn't make my waterline toolpath look right. While running Verify, the cutter digs in at those holes. I'd like to have one surface. How would I go about this? Or filling those 4 holes? Hope I'm asking this in the right way. Thanks for your time. locating ring.mcam

I'm replying to this topic to thank you all who offered help. I got the batch of parts done.

Thanks. Merely doing "Remove Feature" got me there.

I tried untrimming the surfaces around the hex. You can see what happened. Where would I go from here? As far as the toolpath goes, I got Surface Rough Pocket to work, but I don't want to run around the OD of the pin. That's my containment boundary, but unchecking "finish containment boundary" didn't seem to have an effect. 9835 Housing Runner Shutoff Pin rev B.mcam

Quick background: I'm teaching myself surfacing on the job as the need arises. I've posted some questions already and you folks have been very helpful. Thanks. My request today is two-fold. First, I'd like to make a surface over the hex pocket. You can see that it intersects the spherical radius on the floor and that's what I can't figure out. Second, machining the T-shaped slot. I think I have a good toolpath from Equal Scallop, but I'd like it to run past the outside of the part, say .05". Do I need to just draw a bigger containment boundary? Would creating surfaces and then extending them be the way to go? What would be a good roughing strategy? Again, I'd like the tool to run past the outside diameter of the part. Thanks. 9835 Housing Runner Shutoff Pin.mcam

Thanks, CrazyMillman! Here's another related question: Why is it posting a T2 along with the G43 on line N150? I've noticed this only when posting a surface toolpath.

I am cutting a 15 degree wall with Surface High Speed Blend, stepping down .0005". I'm still not getting great smoothness. I'm new to the surface toolpaths. I noticed that when they posted, there's a line for G187 Px Ex. This is a Haas MiniMill 2. I know that I can change the G187 value at the control, but can it be changed within Mastercam?

Thanks. I messed with that as well as Apply Transitions. Something else I missed was under Toolpath Control -> Curves. They weren't going the same direction.

I have attached a file that I'm working on. In the third toolpath, the surface high speed blend, what is going on with the purple moves in the bottom of the slot? it appears also that the lead in/out distance appears to be changing as the depth of cut increases. How can I control this? 9835_Gate-Insert-1.mcam
