Because of the wide variety of machining applications, there is a need for diverse cutting tool materials. The development of tool materials establishes the content flow of this program, beginning with high speed steel tools. Carbide, including its property variables, types, grades and coatings follows high speed steel and makes up the largest portion of this program. Afterwards, ceramic, cermet, and superhard materials like cubic boron nitride and polycrystalline diamond are each featured. Tool failure modes such as cratering, deformation and notching are also examined. You'll learn about the criteria needed to help select the proper tool material for both turning and milling operations.
