No tabs showing up on simulation

[softail96 (Roger)]

I’m using a free version of Carbide Create Pro and my tabs aren’t showing up on the simulation for any of my projects. I have tried adjusting the tab height and I still don’t get them. Would you please shed some light on this issue?
Thanks, Roger

It looks like the two outermost circles are not far enough apart - you likely had an offset of .250, BUT because of rounding errors, the .250 endmill doesn’t fit. Try expanding the outermost circle by, say .050.

Also, the last contour operation has both outermost circles selected, I think instead you want only the inside circle, and change to Outside as the direction.

If you wish to cut as a pocket, you need to have endmill diameter + 10% width at the narrowest point:

so scale the outer circle by:

Done

This will then allow the pocket to cut all the way around in two passes:

The contour toolpath for the outside should only be associated with the inner geometry:

So select only:

Change Vectors:

“Use Current Selection”

and change to Outside / Right:

Ok

Thanks for the help guys.

Is there a way to force it to do the outer pass before the inner so that the surface of the material is cut with a thinner pass?

Leave a roughing clearance and take a finishing pass:

Making vacuum hose adapters

While cutting up vacuum extension wands for this is expedient, it’s a bit problematic given that Shop Vac recently filed for bankruptcy, was bought at the last minute, and production hasn’t caught up. I need a receptacle for the Sweepy 2.0 dust fitting — one option would be to purchase one from Woodcraft, but Carbide 3D sells blocks of HDPE: which looks to be just barely big enough for things to fit. Measuring the hose fitting I get a diameter of ~63.5mm — offsetting that twice we arrive at…

Adding geometry to cut as a pocket with a finishing pass

One technique which is often suggested to avoid slotting is to add geometry around a part which one wishes to cut out and cut as a pocket down to tab depth — here’s one technique for that. In this case, the project is a bevel gauge which will be cut out of 0.0625" (~1.5mm) thick aluminum: [bevelgauge] Due to the narrowness of the angles, an 0.03125" endmill has to be used, so after importing and scaling the file (we will be cutting out one which is 3") we select the perimeter and offset it tw…
