I'm going to be cutting some 4140 steel fixtures on my dual contact 10k robodrill and need to reach about 2.8" deep with a 1/2" diameter endmill for a good bit of the cutting. I thought this would be a good opportunity to try high feed roughing, high RDOC and short ADOC. I'd like to find an effective, low risk approach for roughing larger (still small, shoebox and smaller) steel parts on this machine.
I was comparing high efficiency (100% ADOC, ~15% RDOC, 6 flute Helical .5 Dia x 1.25L) to high feed (4% ADOC, 65% RDOC Helical .5 dia 5 flute high feed mill) using adaptive roughing and wanted to get some feedback from those with experience on 30 taper machines. It looks like HEM comes out about 20% faster for machine time. This isn't an issue as this particular fixture is a once in a while job.
Does the HFM approach do better for chatter in deep features (stiffer tool shank) or lower risk of pull stud failure (primarily upward axial force)? Can anyone share experience on 30 taper high feed roughing?
Thanks,
Mike
