You have your tool entered as a 2" ballnose, when its NOT a 2" ballnose. That will give you the difference between the actual cut and the simulated cut. The geometry is completely different between the tool you entered and the tool you used.

What should I have entered for the bi?
It looked fine in the preview.

That sort of bit is a “Radiused End Mill” according to the software.

I agree - it is not a 2" ball end mill - that is why the preview looks like it.

Ohio has it correct as a radiused end mill.
You just need to know what the radius is.
The tool manufacturer should have that information on their website.

If you have the tool number on the tool you should be able to do an internet search with the tool number.

Reviewing the picture of the bit posted last page I’d say that it is not 2 inches in diameter unless the shank diameter is 1.5 inches. I expect it’s 3/4 or 1 inch at best.

So, not only was the type of cutter wrong but the size too. No wonder the results didn’t match the expectations.

If you look the picture is not of the actual bit the OP has, just the type of bit although the bit the OP has doesn't have the bearing according to the post :lol: :lol:

Here is a pic of the bit, mine does not have a bearing. The file is too large to post.

Phil,
I always enter those kind of bits in the tool database as a "Form Tool". Start by drawing the right side of the bit and with it selected open the tool database. Use the Tool Type pull-down on the right to select "Form Tool". Enter your settings and select "Create Settings". Then finish adding the feed and speed, etc. appropriate for your machine and select "Apply" then Okay

I have a drawing of the tool set and bits from Magnate.Net. They are drawn to scale so I usually just cut one of the drawings in half and use the right half to enter the tool in the database. It's too big to upload so here is a link to the .crv file.

I apologize for the confusion, the picture I posted was just an example of the bit I used. The actual bit has a 1/2" shank and a 1/1/2" cutter. Even so I still don't understand why the cut was different from the preview.

The preview wouldn't match the actual cut because the way you set the bit up (assuming here as you didn't post a screenshot of the bit setup) didn't match what the bit was in reality.

Aspire can only simulate what you tell it the bit is. As others have said it looks you set that bit up as a ballnose when it's actually a radiused end mill. The geometry of those bits is very different to each other.

Phil, if the bit shank in the picture is 1/2" that cutter looks more like 3/4" at best not 2". I'd recommend checking your tool database.

As Adrian suggested a bowl and tray bit is actually a radiused end mill. I like to enter them as a form tool so, if drawn correctly, I can see a picture, shape, and size of the bit when selecting it.
