Cutting tool selection begins with materials, part 2.

Summary


Selecting the right cutting tool for the right job requires some familiarity with the materials used this type of tool. For example, cermets are carbonitride-based materials that are used typically for finish turning and semi-finish turning of steels. Sialons, on the other hand, are ceramic based and used in machining hardened die steels. Descriptions and applications of other cutting tool materials including ceramics, silicon nitride, cubic boron nitride and polycrystalline diamond, are presented.

Cutting tool selection begins with materials, part 2.

In Part II, cermets, sialons, ceramics, silicon nitride, cubic boron nitride (CBN), and polycrystalline diamond (PCD) are discussed.

Ron Edwards has written his book, Cutting Tools, to help people who know how to operate machine tools but often find it difficult to understand the recommendations for tool selection, particularly in the case of hardmetal. In this two-part feature based on excerpts from his book, Mr Edwards discusses the characteristics of nine classes of cutting tool materials.
