CUTTING INSERTS, CONES, EARTH BORING TOOLS HAVING GRADING FEATURES, AND RELATED METHODS |
摘要 |
Earth-boring tools include one or more cutting elements having at least one grading feature positioned a known distance from an initial working surface of the cutting element. Methods of grading cutting element loss on earth-boring tools include comparing locations of wear surfaces on cutting elements to locations of one or more grading features in or on the cutting elements. In some embodiments, a cutting element may comprise an insert having a generally cylindrical body, a substantially planar cutting face surface, a substantially arcuate side surface, and at least one grading feature. In additional embodiments, a cutting element may comprise a tooth having one or more grading features. |
