A cutting insert that is remanufactured from an insert blank using one or more of four unique shapes to provide at least one sharpened edge. The blank can be either a new insert or one that has been dulled and is due to be discarded. The four unique shapes are a compound shape, a radius and flank shape, a bias helical shape and a helical rake shape. The bias helical shape and the helical rake shape can be either positive or negative. The radius and flank shape can be either concave or convex. One or more shapes can be ground on a blank using standard grinding machinery. Performance of the remanufactured insert frequently exceeds the performance obtained from newly manufactured inserts. Further, the expense to produce a remanufactured insert using a discarded blank is far less than the expense to produce a new insert.
A method of remanufacturing a cutting insert comprising the steps of:
A remanufactured cutting insert manufactured by a process comprising the steps of:
The remanufactured cutting insert as claimed in claim 12, wherein said step of acquiring a used cutting insert comprises acquiring a used cutting insert having a cutting edge that comprises a radius and a pair of flanks adjacent said radius, and wherein said step of removing selected material from said used cutting insert comprises the step of grinding a radius and flank shape on said radius and said adjacent flanks of said used cutting insert, said radius and flank shape chosen from a group consisting of concave radius and flank shapes and convex radius and flank shapes.
A method of remanufacturing a cutting insert comprising the steps of:
