Thanks, the Y axis you see above isn't finished. It's just arbirtrarily mated to the x axis to get all the pieces to fit up. Still have model up something for the lead screw and finish up and I'll...

So I've gotten far enough in the design stage that I'd like to start sharing my build. I've got the lathe itself and the basic CNC components. I've managed to install LinuxCNC and get the motors...

I believe he updates the progress on kickstarted. I got curious as well and googled it and it looks like he got enough funding to go forward with it.

So we're running programs from a vendor that used to be cutting these parts for us. The forgings are real expensive so they have built into the program a "Qualifying Cut" for every tool that is used....

All great points and likely valuable to the OP. For myself and likely others I was more interested in satisfying curiosities about the build/design and their legitimacy in satisfying a certain price...

Right, and Turcite is acetal based and the OP is using acetal. So I'm assuming it's similar as far as how they'll wear. Or, a change from plain acetal to Turcite would be a simple swap. Disregarding...

The spec sheet on the Tormach 440 may be misleading but perhaps they use something similar for ways? If the above link doesn't...

Definitely following this thread and look forward to learn a bit more about how it's all gone together. I hope the aluminum/plastic ways hold up just because I think that's a cool idea I haven't seen...

Ya curious as well if the box ways and the slides are all aluminum. If so I'd think they would gall and wear quite fast. Then also how you're getting such accuracy from regular acme screws if you're...

That's awesome! Do you have a build thread?

Don't know why it would do that but you could try using a 2D contour instead of a chamfer operation. The 2D contour operation can be less picky since the chamfer operation has some "thinking" it has...

Nope, definitely not, you can go back and edit the sketch which will update the body that you created from the sketch.

3d contour has a totally different use than a 2d contour. I'm not sure what you're trying to do but you can always model in your own tabs if necessary.

It can do assemblies, I guess as large as you'd want to deal with. It just wouldn't be fun. In Fusion360 every time you start a new file it is in essence an assembly. You can bring in other parts and...

Yes, Fusion is definitely able to do parametric and direct modeling. You are also right that you can double click the sketch in the browser to edit. I just checked, I just usually right click.

I just right click the sketch in the side bar and click "edit sketch." I draw as much as I can in one sketch like you say to make going back and making changes much easier. No need to always make a...

Have not done it myself before but I believe you'll be using the project strategy. I have definitely seen a tutorial on Youtube of it at some point.

You can always model in some "plugs" that you can use in that machining setup so it thinks that the holes aren't there. Then in the next op or setup dont select those bodies.

If your stock is very consistent it doesn't really matter where you set your origin. Like Jon.N.CNC said, if it weren't consistent you can set the origin of the part at the bottom, which guarantees...

If I understand your question correctly, as long as you set up your stock dimensions the same in each setup the part will come out the correct thickness.

Try using avoid surfaces, that would keep the tool path off the surfaces you don't want it on.

I don't know what that is, but it's cool.

I've used scallop to machine a radius when I don't have a corner rounder

You can use tool orientation to do it. Also, there is a way to use multiple work offsets. Even if you don't want the second offset it might work to have it post the way you want. Adding a M00 is easy...

I have never used sprut cam but I don't think I'd bother after trying Fusion360. I also have Bobcad V27 and hate it compared to Fusion.

We have what looks like a similar approach in how we would go about it. You however are much better at hand written Gcode. I've never tried a G97. I feel bad, the drawing I posted wasn't a direct...

I made the worlds simplest drawing of a representation of the feature I'm making. I left out a lot from the actual part and this only took me a minute so if it's still confusing that's why....

I can't post a full drawing but I could post up the basic feature. It's a blind hole so it cannot be flipped and machined from the other side.

I could drill it. Like I think I mentioned however it "passes through" a 3/8" hole as well. That's not a good description but a 3/8" hole overlaps the .5" hole so I cannot drill both holes since...

It is a 2008 HAAS Mini Mill. The dimensions for just the hole really is just .500" to a 4" depth. The only tools I have right now to make the cut is the Harvey tool I listed above and a 1/2" diameter...
