2. Engineering drawing abbreviations and symbols - Wikipedia

   en.wikipedia.org/wiki/Engineering_drawing...

   Typical fields in the title block include the drawing title (usually the part name); drawing number (usually the part number); names and/or ID numbers relating to who designed and/or manufactures the part (which involves some complication because design and manufacturing entities for a given part number often change over the years due to ...

3. Cemented carbide - Wikipedia

   en.wikipedia.org/wiki/Cemented_carbide

   Tungsten-carbide inserts. Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon ...

   Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.

6. Cutting tool (machining) - Wikipedia

   en.wikipedia.org/wiki/Cutting_tool_(machining)

   Cutting tools are often designed with inserts or replaceable tips (tipped tools). In these, the cutting edge consists of a separate piece of material, either brazed, welded or clamped on to the tool body. Common materials for tips include cemented carbide, polycrystalline diamond, and cubic boron nitride. [2]

7. Cutting tool material - Wikipedia

   Can be used up to 900 °C. There are many sort of cemented carbides like ones made of tungsten carbide and cobalt or cermets. Cutting ceramic: They are even harder than cemented carbides but have lower toughness. Aluminium oxide and silicon nitride are used. The latter has higher toughness, but can't be used for machining steel, due to very ...
