Hi all,
Been lurking/learning here for a few years. I've machined a lot of 6061 in the last year and have great results using end mills drills etc. I have a part that needs a groove around the perimeter of the part. the slot is .093 wide x .15 deep. The tool I have is a HSS 8 tooth .625 diameter x .093 wide. I don't have any other info on the tool other than it says USA HSS. I can find lots of speed/feed info on carbide tipped/solid carbide tools, but nothing on HSS. I can make the groove but I'm pretty sure I'm lost on the optimal method. I was constantly clogging the flutes no matter what I tried. I have to take very shallow cuts of .02" at around 300 SFM ,12 IPM with many passes to avoid clogging the flutes. I'm using 100 PSI mist coolant directly at the edge of the tool. I'm trying to reduce the cycle time of this method as it seems to take forever.
Would conventional instead of climb cutting help ?.
Should I punt the HSS tool and get a carbide ?.
Any help greatly appreciated.
Matt
