I'm cutting a dovetail groove for a two inch diameter o-ring in 6061 aluminum. I found that the chips welded to the groove for the first 1/2 inch or so, until some clearance developed. The minimum width of the groove is .125, the speed was 2760 rpm (the max for my machine), the depth is .112, the tool is carbide with three flutes. I used a feed of about 3 ipm.

Any suggestions on how to do this better?

Thanks,

Ken
