Abstract
A cutting insert for milling has a generally perpendicular cutting face that is peripherally bounded by respective main cutting edges and has free faces set at a positive angle and having common edges forming auxiliary cutting edges. The insert has a positive cutting angle and the cutting face has in the region of an adjacent main cutting edge forming a cutting corner a flat or recess which extends into both adjacent main cutting edges.
Claims22
A cutting insert for milling with a generally perpendicular cutting face that is peripherally bounded by respective main cutting edges and with free faces set at a positive angle each of whose common edges form auxiliary cutting edges, and with a positive cutting angle wherein the cutting face has in the region of an adjacent main cutting edge forming a cutting corner a flat or recess which extends into the region of both adjacent main cutting edges, the flat or recess extending at most over half of the length of the main cutting edge and up to the cutting-body corners.
