Machining approach

[Metallic]

Outside of Swarf, what kind of toolpath could be used on this barrel cam? The floor isn't super critical but I know its going to leave a funky finish without another operation.

Thanks

Rolldie...looks like a cam slot....good application for it I think

I usually do this with parallel,  works like swarf  in the end ... A long time ago The Module Works 7 toolpath types were just tweaked into applications and given a new name.  Swarf would revert to Parallel to Multiple curves...

You could use curve or axis sub imo.

The only way axis substitution would work is if the tool diameter is the same as the slot width. 

Assuming you want to use a smaller too so you can have rough and finish passes, and you want to use the side of the tool, you are looking at Rolldie, Curve 5 axis, Swarf, Swarf Milling, and Ruled.  The Multiaxis Parallel and Morph toolpaths would work as well, but they both add complexity to get what you are looking for.

Yes the slots are .128 so nothing standardized tooling wise, was planning to use a 3/32 bullnose

 

Ill mess around with parallel and curve 5 axis as well to see how it goes before finishing with a swarf pass.

 

Thanks!

'unfortunately' i have a 5axis trunnion machine...im struggling getting a good curve 5ax toolpath

try checking Maximum Distance in the Surface Quality setting and set it to .010"

The file will be very large, but this makes a huge difference in the finish I get on our Okuma 5X trunion

will try thanks!
