    Default Saw Video of Tappered end mills drilling holes and milling deep pockets 5 axis.

    Not long ago I saw a video of holes being drilled or interpolated entirely with tapered end mills. At work we call them pencil cutters. And deep pocket walls were also being machined entirely, not just cleaning up the corners. This was done on a trunnion mill. I wanted to show it to one of our programmers as this would help us on some parts. I cannot find it. Anyone ever seen this or know what this type of machining is called?

    Same concept using barrel cutters to 5x deep pocket walls.

    Nice/ cool video for about 20 different reasons.

    So at 4:22 in the video they show a long tapered tool being used; I'm curious as to what the surface finish would be like on that cut as the end of the tool looks to have about half the diameter (at the narrow end of the taper) as compared to the wide end of the taper? As a finish pass I'm wondering what it would look like? Seems that for certain curves and surfaces that would be way more efficient if the surface finish was good/acceptable?
