Hey everyone hope you’re having a good weekend. Couple questions:
Want to cut a 3d project with a 1/8" ballnose. Cutting into poplar.
I’m using a .25EM to do my 3d roughing pass. Usually when roughing with this I leave an allowance of .02" for 3d roughing… software has it auto set to .04" but I figure why not get the relief closer and push the ballnose to cut faster?
Any idea on feed/speed with a 10% stepover and this .02 I can cut with the 1/8" BN? Something i see that concerns me is when I cut with any BN after roughing, the initial passes the entire diameter of the tool plunges into the wood until a path is created, and then the tool begins its 10% step over. This also happens sometimes as the tool moves through different parts of the project.
Maybe not a concern but I definitely turn my .25BN up to like 170ipm after my 3d roughing. Seems to cut fine but erks me on those initial passes, I have to manually decrease speeds in carbide motion.
