Backchamfers

[Anonymous]

Hello All,

I am currently using Bobcad, but I am switching over to iMacs, which Bobcad won't run on, so I am evaluating Fusion 360 to see if it is suitable for my needs.

I have a component which requires some backchamfers machining, I have played around with various strategies but I can't find a suitable one to do what I want.  Its really easy with Bobcad's Multiaxis toolpath, but I can't find an equivalent on Fusion 360.  I have a 12mm dia backchamfer tool that I normally use (DWG attached.)

Thanks in advance

Steve

Haven't tried backchamfering (yet), but I did some side slotting with a disc mill using 2d contour, just playing with heights to widen the slots.

Should work with backchamfering too, in combination with Stock to leave. (?)

Thanks Dave

I still can't get it to run properly, I have programmed it using Bobcad to get this job away, I will spend a bit more time on tutorials etc to see if I can figure something out, I still don't know what I am doing regarding Fusion 360 !

Have you tried using a dovetail cutter in a 2D contour? You may have to add to the bottom and use a - stock to leave but it should work for you.

Exactly what Jeff said, use a 2D contour strategy with negative axial stock to leave to get it to sink down deep enough. I've done it for a lot of parts and it works great once you figure out the additional offsets needed. The simulation works great as long as your defined tool is accurate. I typically use a single point threadmill and that allows me to do 60* chamfers at the top and bottom of a hole.

Hi Guys, Think I have it cracked, the main problem was that I was using the wrong strategy, combined with a few other novice mistakes, I thought I would need a 3D strategy but Trace works fine, together with the right tool shape the simulation is good.

Thanks for your help
