Abstract
A turning insert includes corner surfaces each defined by at least five circle segments arranged in succession between adjacent side surfaces. Successive ones of the circle segments have different radii of curvature. The segments include a center or first segment intersected by a bisector of the corner surfaces, second and third segments disposed on respective sides of the first segment, and third and fourth segments disposed adjacent respective sides of said second and third segments, respectively. The first segment defines a first radius. The second and third segments defining equal second and third radii. The fourth and fifth segments defining equal fourth and fifth angles. Each of the fourth and fifth angles is larger than the first radius. The first radius is larger than each of the second and third angles.
