ABSTRACT:
An indexable cutting insert has at least first and second cutting edges and first and second edge-location surfaces associated with the first and second cutting edges, respectively. The insert-manufacturing procedure includes forming the first edge-location surface with reference to the first cutting edge, and then forming the second edge-location surface with reference to the second cutting edge. There results an indexable cutting insert having at least two spaced-apart chip-removing cutting edges and a plurality of location surfaces adapted to engage a base body for determining the spatial positions of respective cutting edges, wherein each location surface determines the spatial position of no more than one of the cutting edges.
