4th Axis Rotary Adaptive Clearing - Feature Suggestion

Hi,

Originally I was going to suggest a step depth feature for the 4th axis rotary technique - which would be great!

 

But perhaps even more powerful strategy would be rotary adaptive clearing. I am watching this space and simulating the machining of custom mold cores for prosthetic limbs. At the moment its too limited and too expensive. There isn't value for me - yet.

 

My parts have deep sections and shallow sections within the same part with reference to the initial stock. The stock may start as cylindrical or square. A very aggressive roughing strategy is required first off before semi finish the fine finish.

 

How this guy is creating his CAM - he doesn't say. But its what I'm looking for!

Rotary table that can handle roughing metals starts at 10k for 5 inch flange. Also you will put extra axial force on cutter, unless offsetting it from the center and that's Powermill territory already

You can actually use the Rotary toolpath for this style of roughing. You can see the first pass in that video is a full slot.

This isn't to say that a 4th-axis Adaptive isn't valuable, but that your example is doable now. An Adaptive with that configuration is a difficult toolpath to build so no idea if that's on the roadmap or not.

Can i use Fusion 360 for CAM programming of your CNC machine with a rotary axis if you wanted to gradually reduce the amount of  stock material being cut to model that i want on a rotary function?

Rotary doesn't have a concept of "Stock", so any "Stock to Leave" is just going to result in a fair bit of wasted cutting motion. You're typically better off indexing to a position, locking the rotary axis and doing a 3D Adaptive on a few sides of the part.
