Aspire V10 Toolpath ??

[njload]

Still in the learning curve here but was wondering what kind of tool-path is needed to create the Sloped carve on the Mexican Train domino's station.
Designing it is no problem but I have no idea how to create the tool-path to slope out the ends.

Picture included. Hope I am explaining this right.

As usual in Vectric, there are more ways than one to attack the problem. It looks like a flat topped dome. I created a dome from Create Shape from vector outline. Then I drew a rectangle to represent one of the cutouts. I used circular copy to create 8 rectangles. 8 is just a guess. I have no idea what the total board should look like. Select the 8 rectangles, and the dome, and use Clear area of selected component inside selected vectors. I drew a circle and used a 2D Pocket Toolpath to shave off the top by 0.15"

I would use a moulding toolpath with a large ballnose bit. Draw a circle for the moulding toolpath rail, and a slanted line for the profile.


Edit - don't use my tool feed and speed settings - way too fast for a small machine.

Thanks to both replies, I need to wrap my head around what you both did. I was messing with the create shape dome but wasn't sure about the rest.

Thanks again.

You guys are great.

dealguy11, still trying wrap my head around the molding tool-path and was wondering how to change the thickness of the stock to reflect in this tool-path.
I know how to change the job setup and when I do this I get a warning that the "cut depth exceeds material thickness" in the swept profile tool-path. This is when
I changed to .75" thickness in the job setup.

Any help is more that appreciated as I don't want to just copy your generous help but I want to learn from it.

The depth of the moulding toolpath is defined by the height of the sweep vector. In the example I sent, if you click on the slanted vector to the right of the work area and then click on "Set selected objects size" you will see that it is a little more than 1" in height. If you modify this vector in the Set Selected Objects Size dialog so that it is only 1/2" high (make sure you unclick "Link xy" when you do this so it doesn't change both dimensions) then it should work in 3/4" stock.

Edit - Actually, anything less than 3/4" will work. I picked 1/2" because it looks like there is about 1/4" of material around the edge of the shape in the picture you provided.

Thanks again, really appreciate your help.

Hey guys. Like this Mexican Domino Train Station But can't read it on my VCarve Desktop Software. Any chance someone can translate it for me? Apologize if this cannot be done but hopefully it can... I cut 3D images all the time...

Cheers!

You can also make a slope using the fluting toolpath and closely spaced vectors. I use an end mill and vectors spaced at 1/4 of the end mill diameter. Note that the cut area will be beyond the selected vectors by the tool radius, but the sloped area will end with a flat at the lowest point . A conical surface like this would be cut using radial lines. The fluting toolpath will cut faster than a 3D surface, but uses a different tool.

Thanks Mike. I get it and had not thought of that approach. What do you use as "vectors"; a line, arc?

[FixitMike]

I use straight lines as vectors. For this example I used a 1/2" end mill with the vectors spaced about 1/2" apart at the outer ends. Note that the cut extends beyond the vectors by the tool radius, which means there will be a 1/2" flat at the lower ends. I profile cut inside the cut for this example.

Correction: 1/8" apart, not 1/2". I use 1/4 of the diameter of the bit used to get a reasonably smooth surface on a moderate slope.

Thanks again Mike. Hmm, want to fully understand your approach. It seems that to make a dome shape, using circular vectors stepping in at 25% of the End Mill diamter, in my case, 1/4" End Mill, thus 1/16" steps would do the trick. So am confused about your use of straight lines as vectors. Also, not sure what I am looking at in the image you attached...
