Abstract
The multitude of cutting materials already in existence increased further with the appearance ofpolycrystalline diamond (PCD) some 25 years ago. Ceramic show no chemical affinity to most machiningmaterials, but are very brittle. Natural diamond, the hardest known material, is very wear resistant, but alsosensitive to impacts and difficult to shape. The main advantage brought about by the development ofpolycrystalline diamond is the partial combination of the exceptional hardness of diamond with the toughness oftungsten carbide. This paper is presenting a series of the general considerations on cutting tools which have thecutting surface made of polycrystalline diamond. There are also presented some original results concluded by theauthor, based on experiments made with the tools mentioned before, which have different design values.
期刊介绍：
International Journal of Energy, Environment, and Economics publishes original research papers that shed light on the interaction between the utilization of energy and the environment, as well as the economic aspects involved with this utilization. The Journal is a vehicle for an international exchange and dissemination of ideas in the multidisciplinary field of energy-environment-economics between research scientists, engineers, economists, policy makers, and others concerned about these issues. The emphasis will be placed on original work, either in the area of scientific or engineering development, or in the area of technological, environmental, economic, or social feasibility. Shorter communications are also invited. The Journal will carry reviews on important issues, which may be invited by the Editors or submitted in the normal way.
