Fusion 360 Tool Paths: 2D, 3D or combination?

[crucibleoptics]

I tried using 2D contour to completely remove the material, but when I use the simulate, as you can see in the pictures, some material appears to be left attached to the back of the model. Any recommendations are greatly appreciated.

Hey! It's good to see you. I thought about you the other and your previous thread about making a frame for some reason.

Can you post the fusion file? If it's leaving material attached on the bottom I think it's a depth issue.

I think he meant the simulation is showing it. Hasn't actually run it yet. At least that's how I read it.

I know, I think it should show it being cut through though.

Mine never has. Always leaves a small "skin" of material at the bottom but the actual cut is all the way through.

I do have a question, why two contours selected crucible? If you're doing a 2D contour you only have to select the bottom contour.

I selected the edges of the bevel on the inside of the frames because I wasn't sure if the tool path would recognize the edge unless i manually selected it.
Here is a link to the file stored through Fusion's cloud. a360.co/2fI2ykI
Another issue I seem to continually run into is the XYZ axis shifts directly to the center and opposite side of the model while assigning tool paths, after I place it in the correct spot during setup in the lower left corner.
Doing some research I may be able to mess with the settings when creating a new design, but it might just be a bug.
As always, I appreciate all of the feedback and help you guys provide!

On this particular design if just doing regular 2D contour, you need only select the bottom contour for each area. So the outside, then the two pockets. Just got off work. I'll look at it in a minute.
As always, you're welcome.

With the origin point shifting.... it sounds like you may be doing a new setup for each tool path. Is that what you are doing or have a misunderstood? Usually, you would want all operations on one face of the material to be done under one setup.

I can tell you right now, your origins are all screwy lol. I've adjusted the file, fixed those, and selected your contours. You need to adjust feeds and speeds, DOC, all the details as I didn't mess with those. Make sure when you are designing, you make it easy on yourself and start your sketches on the plane that puts Z up, y to the back and X to the right. IF you don't you can adjust it in CAM setup. The problem was, you had your sketch origin wrong, then in CAM on the first window of setup, you had it set to "model origin". SO you were telling it to reference an incorrect orientation. Also, I would not use a ball endmill like you had selected, I would use a flat on the contours then have separate operations with the ball for the recess if a curved face is what you were going for there.

I select the setup folder and move the point to the lower left with the z-axis pointing in the right direction.



Immediately after selecting 2D contour the axis shifts and begins designing a tool path using the wrong side of the model.



I tried adjusting the axis settings through preferences as well as changing the view cube to correctly reflect the sides but still run into the same problem.

aforww, Thank you so much! I haven't adjust settings yet but I will do some more research and find out what the optimal recommendations are for aluminum.

I'll play with it after I get some sleep and make you one in the manner I would mill it. My intention is not to do it for you, but to give you some perspective. Personally, I'd use 3D adaptive on the lens holes, then 3d contour to finish and put the chamfer on the inside, then 2d contour on the outside. But that's just me.

I will re-watch the Fusion 360 videos and use the 3D tool paths you mentioned.
