How to use Dynamic Core Mill inside out

[VINK]

Hello all,

 

I have a part that has a ~1.75" thru hole in the center of a non-circular pocket. How can I use to Dynamic Core Mill to mill the pocket after the thru hole has been cut. DCM would be the most efficient tool path if I could just figure how to use it inside out.

 

Thanks in advance for the help.

Maybe I'm missing somthing but shouldn't dynamic area mill work.

Core mill is used in instances where you have a boss ( core ) protruding from the part and the toolpath works from outside to inside. As mentioned above, area mill works from inside to outside ( pocket/ cavity )

You could try dynamic rest mill and use your drill op in the rest material setting. If the drill op doesn't do it, a "dummy" mill op that you don't post might work better.

Use Area Mill to machine the entire pocket then drill the thru hole, I ve been trying to machine this but it always wants to machine from the center out.

Got it to work with a dummy PKT rough, rest now starts where the pkt left off the 1.75" through hole and dynamically approaches the rest of the PKT.

Thanks for the input guys,

 

At first what I was trying to do was dynamic area mill the 1.75" hole first but did not want to use it again to do the pocket above because the majority was already cut. If I use some false geometry to avoid the center 1.75" hole it became a very inefficient tool path because Dynamic Area Mill approached it as a ring shaped pocket. That is why I figured if dynamic core mill could work inside out it would be a very efficient tool path.

 

I ended up approaching it like you suggested initially Greyman, I Dynamic Area Milled the pocket first and then contoured the central 1.75" hole (should mention the part is 3/8" thick and the pocket is .300" deep so the floor is pretty thin anyway. I attached the pic of the part.

 

Although this part didn't demand it I still think it would be great to use Dynamic Core Mill inside out.

 

Again, thanks all

I would use opti rough.

 

Opti rough I put that sh%^@ on everything. LOL
