摘要

A cutting element for use in a cutting operation, comprising a cutting edge capable of cutting out material from a workpiece during the operation, to form therein a workpiece corner of angle a. There exists at least one view of the cutting edge in which a portion of the cutting edge is delimitable by a first and a second line oriented tangentially to the portion of the cutting edge portion at respective tangency points A and B. The lines form therebetween a cutting angle corresponding to the workpiece corner angle a and have a vertex O. For a bisector of the cutting angle intersecting the portion of the cutting edge at a point C, the projection C' of the point C of the portion of the cutting edge on a line OL passing through the vertex O perpendicularly to the plane of the one view is located between projections A' and B' of the respective points A and B of the portion of the cutting edge on the line OL.
