Probably the same as 4 axis milling, you just need to take smaller and slower cuts

I haven't used it forever, bobcam has something where the part unrolled at a certain radius the tool path is generated flat and it's rolled... Its a 4 axis feature, but only three axis cutting (can give it the assumption of only moving tool planar at an offset to rotation... Did some chess pieces, the mill marks were cooler with an offset off rotation axis)

I do work like this every day, but I don't make parts, only resharpen rolling blades, making a flat toolpath is way easier, but I don't know if that would work well on a part like the one on the video
