Guys my QCTP come in from All Industries so my first project for the mill is to actually make something which is the T-nut for the post.Well I am thinking piece of cake nothing to it,well I was wrong what you see in pic took me several hrs.I started out using a 3/4 end mill which from All Industries taking small passes even though I watch a Youtube of Tom's Techniques making the cut in one pass which is about 1/4 x 1/4 I just thinking thats to much for this beginner.I was going to make a pass which was .030 which did OK.On that setting I would rotate the nut and make pass on that side after making several passes I notice that I was not seeing chips and I think it was just rubbing and not cutting on back side with the part on edge.So after awhile I would lay the part flat and make some passes which was little better but I think I destroyed my bit.But the nut fits but loose which I was going for a good fit just to see if I could do it but no go.Guys at first I was making climbing cuts did not realize it till my bit was dull but I was using cutting oil.For while I was at 160rpms hand feeding then I tried 500rpms hand feeding but still like it was pushing against the part.I think that my rpms was way to low plus making climb cuts for the most of the part dull my bit.I want to learn from this but what else did I do wrong or should have done?All this base no problems with the mill itself but going to recheck the head and tram the vise again.
