I agree. I don’t even put them in the drawing. I have had a similar problem also making threads in large bronze prop nuts.

Fusion 360 chamfertutorial

Attached are screenshots of a speed handle I made recently. I have modeled the chamfers that I wanted and successfully machined them using the following parameters using the 2D chamfer tool path. This is a 1/4" Diameter, 4 Flute chamfer tool with a .060" flat tip. The chamfer tip offset needs to be greater than the chamfer being cut. Feel free to message me if you need any further help with this.

What is the width of the chamfer on your part? I believe the the offset must be greater than the width of the chamfer. I don’t model chamfers in my designs so I’m not sure if this helps. I do all my chamfers in the CAM operations.

I’ve not seen any good solutions for modeled chamfers. You’d think it would be the easiest way to tell fusion what you want. I just stopped modeling them based on everything I read and suggestions from others. Way easier to program without them currently, but I’d much prefer to include them in the model.

I have been going to this store for a long time, ever since I moved to Lebanon. I went in July 22, 2018. At 11 am. And I had the rudest service over wic products that I have ever had. I was at the customer service desk getting checked out and the older lady behind the counter was upset because we had wic products. She slammed all of our food products including are eggs on the counter which in return broke 5 eggs and damaged our bread. I will not come back to this store. The employees are disrespectful and unappreciative. My business will from now on be at Walmart. It's sad how people get treated for things they have no control over. And it's really sad considering I enjoyed going to this store up until today. And this is the second time she has treated us this way. I will not be back

Fusion 360 chamfertoolpath

I have had good luck using 2D Contour on the bottom edge if the model has the chamfers, or 2D Chamfer if I didn’t model them.

The chamfer is in the drawing. Top edge of chamfer is selected, height is model top, bit size is correct 1/4" 90 degree, chamfer width 0, chamfer tip offset 0.1, chamfer clearance 0.

I believe NYCNC has a great tutorial on this topic. I have no idea if it still valid for this build of fusion 360. They do it modeled and not modeled. I can see benefits to them both.

I am having a problem with chamfering a part I have cut. The toolpath and simulation looks to be correct, however the bit does not touch the part. I have tried everything I can think of.
