Estimating the term…
A cutting insert includes a body made of a ceramic material. The body has a first surface, a second surface and at least one flank surface extending between the first surface and the second surface. The first surface includes a chip forming feature extending in a radially outwardly direction to a cutting edge and extending in a radially inwardly direction to an inner edge. The chip forming feature includes a front wall that slopes downward from the cutting edge radially inward toward a rounded bottom surface and a back wall that slopes upward from the rounded bottom surface radially inward to the inner edge. The chip forming feature can include an optional land surface between the cutting edge and the front wall.
A cutting insert comprising a polygonal body made of a ceramic material, the polygonal body having a first surface, a second surface and at least one flank surface extending between the first surface and the second surface, the first surface including a chip forming feature extending in a radially outwardly direction to a cutting edge and extending in a radially inwardly direction to an inner edge, the chip forming feature including a linear front wall that slopes downward from the cutting edge radially inward toward a rounded bottom surface, and a linear back wall that slopes upward from the rounded bottom surface radially inward to the inner edge, wherein the rounded bottom surface intersects each of the linear front wall and linear back wall.
