Most of the slides I have made allow a land on the outer corner of the male slide of up to 2mm.Female Dovetails themselves are undercut, any form cutter will only produce a radius of gyration.OP did say female, with a roughing slot) I have a horiz.
The side of the cutter mills the sidewall of the internal dovetail while the angled face mills part of the floor. Download anime descendants of darkness sub indoIts difficult to get all the faces into the proper relationship with each other. Hold the part in 2 vices and mount the 2nd cutter I showed above so it will cut a slot, DONT CUT YET But you see it would cut a slot. The END view will look like the top porton of K see it now Heres the math. Lets asume the cutting speed is 80 Ftmin The RPM is 3.82 x 80 pick a 4 inch cutter.so. RPM That cutter has 16 teeth and will cut at 0.008 Chip per tooth Feed is 16 x 0.008 x 75 9.6 inmin Climb mill (so all the cutting forces are directed into the table) and take it all in one cut and flood the coolant to it. Similar tooling works as well Hor. Vert. (just differing arrangements). Send them out to get the correct positive rake ground or do it with a dremel. Grind the extreme end of the tips off 18 can be cut in 3 mins I guess my answer dont apply. I guess the parts I have run had a much tighter tolerance than the norm. Im just dieing to know what kind of tolerances the part calls for now though. I just dont see a female dovetail being cut as some have mentioned, with the tolerances being tight. What has worked best for our female parts is what you are doing, slot the middle first with a roughing end mill, then finish with a conventional dovetail cutter. Harvey Tool Carbide Miniature End Mills, Diamond End Mills, Carbide Long Flute End Mills, Carbide Long Reach End Mills. And I dont try to pretend to be as you say special talent,high tolerance guy or however you put it. ![]() I just put in my 2 cents, and as I said it probably didnt apply, after I realized we were talking about something that the tolerance was more open than what I was thinking. And for the record I have never ran a dovetail where it would have been ok to grind the ends down. I wish I could say I have though, because it sucks working on keeping them on there. But I dont recall saying anywhere in my post there wasnt ever such a drawing out there that would allow this. For the hard of thinking of course). Engineers can be silly at times, as Im sure you are aware of. Sometimes the tolerances are way tighter than what is needed. The tone of a post can be hard to judge, especially when people come with different experiences and fail to imagine other possibilities, (myself included ).
