I wrote. "The "secondary micro convex bevel" is actually a full blown secondary bevel. The cutting edge is now the secondary bevel and the Scandi is rendered as cosmetic, where the edge could be a saber grind. The secondary grind has cut into the Scandi edge deep enough to have the cutting edge be a much more obtuse angle.

Micro-grinding which uses tool with a diameter of less than 1 mm to remove material is the final procedure of machining micro-parts, and its machined surface quality directly affects the service life of workpiece. In this paper, micro-grinding experiments of nickel-based single-crystal superalloy with only one grain were carried …

The EWR for internal micro-grinding can be expressed as: (1) n e f f (int) = n s t = n s ⋅ l / v w = 60 n s a p d s d w d s + d w / (n w π d w) where t is the time needed for a contact length l, d w is the hole diameter, and d e is equivalent diameter. For internal micro-grinding, de can be expressed as: d e = d s d w / (d s + d w).
