摘要 |
An insert for a milling cutter has a chip face and a bottom face which are interconnected by side surfaces. The intersection of side surfaces with the chip face forms four cutting edges. Each side surface is beveled at its intersection with a cutting edge to form a planar clearance face, the width of which increases toward one of the cutting corners. Each cutting edge includes a main edge portion, a corner edge portion, and a secondary edge portion. Each secondary edge portion extends inwardly from an associated secondary edge at an angle no greater than four degrees. At each corner, a secondary edge portion of one cutting edge forms an actual angle with a main edge portion of another cutting edge greater than ninety degrees. The insert is mounted at a negative radial rake and a positive axial rake such that such actual angle presents to a workpiece an effective angle of ninety degrees to cut a ninety degree shoulder in the workpiece. |
