That example for engagement in outside versus inside corners is important, especially if you do much stainless or titanium. I use Fusion's feed rate optimization when the inside radius is within 150% of the tool radius. So if I'm cutting an inside contour and the corner is a 4mm radius and I'm using a 6mm diameter (or 1/4" - 6.35mm) end mill, I'll use optimization to reduce the feedrate into and through the corner. It takes some messing with to get it figured out, but you can see the feedrate change in the simulation so it doesn't require it be figured out with the mill. It makes an amazing difference, especially if I'm doing a final pass on something like a large inside rectangle. Feed rates can stay high except in the corners. That sound when you plunge an end mill too into an inside corner too rapidly, even though the straight section sounded great, is an awful sound. Anyway, Great video!

great vid. also remember that with all 90° tooling, anything above 50% or more radial engagement, APT is equal to chip thickness.

Jason, That was one of the clearest messages I’ve seen ANYWHERE on KZbin 👌 Thanks for taking the time to do these education vids. Regards Robert

Hi Jay Another great video. I think a message to designers is to be careful about specifying the size of the inside radii. If it does not matter make it big. As Bill ponted out below another reason for the spike on inside radii is that the feed rate is the centreline of the cutter. Hence the feedrate at the cutter face is much greater for inside radii.

Good overview of tool engagement. Something I found interesting, I use Fusion 360 for my CAM and the the software actually uses the tool engagement angle when it calculates the tool path for Adaptive Clearing even though the input is radial cutting depth.

great video the old saying there's no replacement for displacement also relies on your engine builder so this can go along with the CNC builder as well because we have a SBF that eats big blocks for breakfast :) until a certain point there's always someone faster

Considering the nature of the fusion 360 or hsmwork for solidworks 3D adaptive tool path where when machining a pocket it renders mostly arcs and lots of radiuses with hardly or possibly any “ideal condition” straight cuts, how would you determine the true engagement angle and why doesn’t the cam side continually adjust feeds and speeds to maintain a constant chip load and tool engagement even on inside and outside corners?
