  • Patent number: 5957755
    Abstract: 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.
