PCT No. PCT/SE95/01260 Sec. 371 Date Apr. 28, 1997 Sec. 102(e) Date Apr. 28, 1997 PCT Filed Oct. 25, 1995 PCT Pub. No. WO96/12583 PCT Pub. Date May 2, 1996The present invention relates to a milling cutting insert having an upper side, a bottom side, and flank surfaces connecting the upper and bottom sides. At each operative cutting corner there is a projection which is depressed relative to the adjacent main cutting edge and corner cutting edge. At the front upper edge of the projection is the wiper edge that generates the surface on the workpiece. By tipping the cutting insert axially positively and radially negatively, the horizontally located wiper edge may be tipped frontwards into contact with the workpiece, while the vertically located wiper edge is tipped backwardly, so that it does not reach the workpiece. In this way an improved axial clearance is made possible and an undesired groove in the workpiece is avoided, which would otherwise be caused by the vertically located wiper edge. |
