This paper deals with the design and fabricate the air operated glass cutting machine. Cutter is a common tool used in various cutting shape for a variety purposes. In this project, a glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack ....etc

he Cam Hammer
Leonardo da Vinci s Cam Hammer

Leonardo s invention the cam hammer is another example of thinking centuries ahead of his time. This machine would be used extensively several hundreds of years after his death during the industrial revolution. They would be powered by Steam engine and could hammer at up to twenty times per second. They were used to draw out the sheet metal for ships and armored machines for war such as the tanks in world war 1.
Below is his original drawing for the cam hammer

A cam valve (or more properly, a cam-actuated valve) is a directional control valve, and is available for both air and hydraulic operation. For air service, 2-way, 3-way, and 4-way cam valves in sizes up to 1-inch are available. For hydraulics, most cam valves are 2-way, either normally open (N.O.) or normally closed (N.C.), but are not generally available larger than 1/4 or 3/8-inch size. However, as shown in these circuits, they can be used to pilot larger valves.

For applications like those described here, in which the action takes place ....etc

Motor Operated Valve (MOV) is an important element of the Plant & Piping system. These valves are usually large and are used for various applications such as the pump reject of etc. Motor operated valves are often called as valves On-Off engines are used to fully open or completely close the valves in the pipes. For example, the cooling water pipes, the processing pipelines where fluid control is not needed, the engine valves running can be used to allow fully or stop the flow entirely. These valves are not used for limitation purposes because ....etc
