Veneers are typically cut oversize before being laminated to their wooden substrates. [1] A laminate trimmer equipped with a bearing-guided flush trimming bit can be used to cut the veneer to its final size. [2] The bearing guides the bit around the outside edge of the wood substrate, making a clean cut exactly along the edge.
An important application devised in the 1920s was the use of phenolic laminate fabric for gears; cut on conventional hobbing machines, the gears were tough and quiet, which was important for automotive timing gears. By 1932, the Formica Insulation Company was producing 6,000 gear blanks per day for Chevrolet and other car makers.
Leobardo Segura Meza, 27, of Pacoima suffers from silicosis, an incurable lung disease that has been afflicting workers who cut and polish engineered stone high in crystalline silica.
Shearing, also known as die cutting, [1] is a process that cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations. [ 2 ]
A rail repair dutchman is typically a 4–6-inch (100–150 mm) long piece of rail that is cut in advance for the purpose and carried by a section crew. If the gang finds a rail with a chipped or broken end, they remove the connector plates ( fishplates ), cut out the damaged section, replace it with the dutchman, and bolt the connectors back ...

Chip formation is part of the process of cutting materials by mechanical means, using tools such as saws, lathes and milling cutters.. The formal study of chip formation was encouraged around World War II and shortly afterwards, with increases in the use of faster and more powerful cutting machines, particularly for metal cutting with the new high speed steel cutters.
The cutting surfaces of a milling cutter are generally made of a hard and temperature-resistant material, so that they wear slowly. A low cost cutter may have surfaces made of high speed steel. More expensive but slower-wearing materials include cemented carbide. Thin film coatings may be applied to decrease friction or further increase hardness.
