Available in PDF, EPUB and Kindle. Book excerpt: Interest in ceramics as a high speed cutting tool material is based primarily on favorable material properties. As a class of materials, ceramics possess high melting points, excellent hardness and good wear resistance. Unlike most metals, hardness levels in ceramics generally remain high at elevated temperatures which means that cutting tip integrity is relatively unaffected at high cutting speeds. Ceramics are also chemically inert against most workmetals.

Available in PDF, EPUB and Kindle. Book excerpt: New and improved ceramic cutting tools for the machining of AISI 4340 and D6AC steels were developed. The new tools showed a substantial improvement over commercially available Co-bonded WC and Al2O3 based tools in the machining of the above metals. These new tools resulted from screening and fabrication studies on 9 refractory materials. The tool fabricated from the initial composition 60 Wt% TaN - 40 Wt% ZrB2 by hot pressing under suitable conditions proved to be superior to all commercially available tools tested during this program. Other ceramic systems which exhibited promise for the fabrication of tools for the machining of AISI 4340 and D6AC steels were: 50 Wt% TaN - 50 Wt% TiB2, and 50 Wt% TiB2 - 50 Wt% TaC. A machinability parameter study was initiated and in several cases these parameters could be qualitatively correlated with the cutting test performance of conventional carbide and ceramic tools. Ultrahigh pressure, high temperature experiments resulted in the synthesis of LiSi2N3 and MgSiN2. These compounds hold promise as additives for the densification of Si3N4. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: New tool materials were developed to achieve increased cutting efficiency. High-speed steels of the M2 type were enriched in titanium, hot worked, then solid-state carburized. These tools showed a permissible cutting speed increase of about 35% compared to commercial 'RC 70' type high-speed steel when used for turning AISI 4340, RC 44. Similar increases in cutting performance were measured for cast-to-shape tools based on M1 high-speed steel containing 10% V, up to 2% Ti and 3.5 % C. Age-hardenable cobalt-base tool alloys were prepared by the hot working of atomized powders. The most promising alloy was Co-45Cr-15W-2.5C, which exhibited a permissible cutting speed increase of 120% over the commercial cast cobalt-base tool alloy in turning the RC 44 steel; a speed increase of 35% was achieved in turning AISI 4340 at RC 52. Cemented carbide tool alloys having matrix melting points near 1800 C (3270 deg F) were prepared by liquid-phase sintering or arc-melting Compositions in the Cb-V-C and Ti-V-C systems were the most promising. Initial studies of arc-melted 80Hf-20Ta, nitrided at 1930 C (3500 F), showed a cutting speed capability similar to that of commercial alumina tools on AISI 4340, RC 44.5. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Hard machining is a relatively recent technology that can be defined as a machining operation, using tools with geometrically defined cutting edges, of a work piece that has hardness values typically in the 45-70HRc range. This operation always presents the challenge of selecting a cutting tool insert that facilitates high-precision machining of the component, but it presents several advantages when compared with the traditional methodology based in finish grinding operations after heat treatment of work pieces. Machining of Hard Materials aims to provide the reader with the fundamentals and recent advances in the field of hard machining of materials. All the chapters are written by international experts in this important field of research. They cover topics such as: • advanced cutting tools for the machining of hard materials; • the mechanics of cutting and chip formation; • surface integrity; • modelling and simulation; and • computational methods and optimization. Machining of Hard Materials can serve as a useful reference for academics, manufacturing and materials researchers, manufacturing and mechanical engineers, and professionals in machining and related industries. It can also be used as a text for advanced undergraduate or postgraduate students studying mechanical engineering, manufacturing, or materials.
