Milling a slot

Hello!

I have a 5 1/2" x 3/4" slot with 1/8" corner radius that id like to mill with two different size endmills. A 1/2" flat endmill to cut the bulk of material, then a 1/4" flat end mill to come in and clean up the walls and get the 1/8"R corners. Im having trouble getting the 1/4" endmill to only clean up the walls. I am attaching a picture for clarity.

Are you looking for something like the image below, if so try the attached file, may help 🙂 🙂

That helped a ton! Changing the bottom height to "selected contours" changed everything. Anyway you could explain that so I know for future use? I usually just select "stock top" then enter the height in a negative value to get the tool to the depth I need.

Also in your simulation it shows the stock as a solid piece. I cannot seem to get that on mine, any suggestions?

I used the Selected Contours as that is usually the best option for doing something like this, it is in my opinion more specific and accurate.

You should get a solid stock if you uncheck the Transparent option as in the image below. Hope this gives you a bit more clarity 🙂 🙂

Gotcha! I might do it that way from now on. 

 

As far as the transparency, when I start my simulation the slot is already gone. It doesn't show the material being machined. It just shows the toolpath. 

 

see attached 🙂

In your image you have the Transparancy checked so you need to uncheck it, also your image doesn`t show what you have the Opacity set to, if that slider is all the way to the Left then what you will get is as shown below.

I tried tampering with the settings, still cant seem to get it 😕 I took another screenshot, looks like my settings are pretty similar to yours.

 

I appreciate all the help!

It doesn't look like you ever shared your Fusion file. I suspect what you're seeing is because your Stock is the same as your Model, but that's just a guess. Could you share your actual Fusion file here?

You were correct! I changed the stock option from "from solid" to "relative size box" with no additional stock and it worked. Greatly appreciated!

That would be correct, I had to create a file to show as a example, always best if you can upload your Fusion f3d file 🙂 🙂 🙂
