Finally tested Dynamic Milling

WOW! I never thought you could move Aluminum like that with just 7500 RPMs!

Just did a simple .75 deep pocket with a 3FL E.M.

7500 rpm

215. IPM

18 % step over

.75 DOC

.2 Rounding R

.01 micro lift

 

The one (simple) thing I haven't figured out is how to chain or cut out an open pocket

Can you not literally have an open chain? I've tried both solids and just simple geometry. Could someone please explain this process of properly cutting an open pocket w/o just tricking it by extending lines.....

all chains have to be closed.

You can use 2 chains though. One for the stock and one for the island. I used to hate the open pocket method, but this works awesome!

it's a bit tricky to get open pockets to work

 

you got to chain the outside of the pocket

the first chain is the complete outside rectangle (use as stock) and to cut the open slot you got to chauin the green perimeter. it's hard to explain in a few words....

Thanks guys! Can't wait to try out that path on a few of our parts!

Here are some tips:

 

If you chain more than one thing, the largest area is the cut area. Every other chain will be an "island" or something the tool will avoid.

 

In the example above, you must chain the big square, because you want to cut it, and the U shaped "island" because you want to avoid that.

 

I will post some pics to make it clearer.
