摘要： Embodiments of methods are disclosed for characterizing a tested polycrystalline diamond (“PCD”) element, such as a PDC cutting element. In an embodiment, a method for characterizing a tested PCD element is disclosed. An initial volume of a PCD element is measured using a coordinate measuring machine (“CMM”). A workpiece is cut with the PCD element so that the PCD element develops a wear flat. A post-cut volume of the PCD element is measured after cutting the workpiece using the CMM. A wear volume of the PCD element is determined at least partially based on the post-cut volume and the initial volume of the PCD element.
