opti rgh, hs surface restmill ???????

I’m trying to efficiently rough out this part while the material is at an 42 deg angle. This brings the floor of the pockets normal to z. I first tried using suface high speed rest mill, but I don’t like the movement of the cutter as it over engages the tool nearly 80% of the time. 15% of the cutter should mean 15% not 40 % when it moves into a new direction. ( trochoidal cuts not available in rest mill)

 

 

My next thought was to try the super fancy J opti rough. This gives a great tool path, but like surface high speed core mill it tries to cut what it thinks is the stock, but is just air. Then I tried trimming the opti rough path to get rid of the air cuts and it violates my part.

 

 

I may be missing something, so feel free to recommend another option. Im out of ideas for today.

 

 

Thanks, Damian

update.

 

i set all retracts to INC and no more violation. but i do have an invalid arc you can see in the 3d pic. any thoughts on this?

Still there has to be a better way to handle stock that i dont know of.

I recently did a part that was @ a 20 deg angle and I had to use toolpath trim funtion to get the resultsI wanted.

make an stl of the stock

and use the stl file for "Rest Material" in the High Speed Rest Rough Toolpath

Damian, the ultimate solution is the Cimco HSM Performance pack. The 3D adaptive clearing is like Optirough, but it recognizes check surfaces and has STL recognition for stock. It's just awesome.

I think we're all anxiously awaiting "Opti-Rest". Until then it is either HST Restmill, use the trim function, or purchasee adaptive clearning.

thanks for the info. The cimco hsm looks like a great add on.

 

looks like i will just leave it alone for now and use the rest mill.
