Some of the Cincinnati local foundries which supplied to the machine tool company included the Blackburn Foundry, Buckeye Foundry Company, the Steel Foundry Company (Cincinnati) and others. In 1889 the screw and tap business was sold off, as the company focused on machine tool business. It was renamed as the Cincinnati Milling Machine Co. (CMM).

An alligator shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. The jaw size can range from 4 to 36 in (100 to 910 mm) long.
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]
According to The New York Times, the Army has started to "wikify" certain field manuals, allowing any authorized user to update the manuals. [4] This process, specifically using the MediaWiki arm of the military's professional networking application, milSuite, was recognized by the White House as an Open Government Initiative in 2010.
Fig. 1. A shear formed product: a hollow cone with a thin wall thickness. Shear forming, also referred as shear spinning, is similar to metal spinning. In shear spinning the area of the final piece is approximately equal to that of the flat sheet metal blank. The wall thickness is maintained by controlling the gap between the roller and the ...
Rotary shear slitting. Male and female circular knives, or as they are also called, top and bottom shear-cut knives [2], engage to give a scissor cutting effect. This system is used widely on paper, films and foils. Although the knives take longer to position, they stay sharp longer than razor blades.
Figure 8 Figure 9. Assume a material element under a state of stress as shown in Figure 8 and Figure 9, with the plane of one of its sides oriented 10° with respect to the horizontal plane. Using the Mohr circle, find: The orientation of their planes of action. The maximum shear stresses and orientation of their planes of action.
