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).

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]
Grab the LAWN SHEARS that are on the side of the cabinet. On the top left side, there is a piece of paper on the wall, click on the paper and it will move to the side, revealing a strange carving ...
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.
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.
Shear and Bending moment diagram for a simply supported beam with a concentrated load at mid-span. Shear force and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear forces and bending moments at a given point of a structural element such as a beam.
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 ...
