design and fabrication of air operated mirror cutting machine

abstract

the aim of the project is to design and fabricate the air operated mirror 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 is required to be formed uniformly.
a glass cutter may use a diamond to create the split or more commonly a small cutting wheel is used made of hardened steel or tungsten carbide 4-6 mm in diameter, with its cutting edge ground to a v-shaped profile. some glass cutters hold a small amount of cutting oil, which both lubricates the wheel and prevents the split in the glass from closing. when properly lubricated a steel wheel can give a long period of satisfactory service. the improvement of cutter which is design and fabricate of a pneumatic cutter. this cutter also safe to use when press the on button the high pressure air comes and leads the cutter to cut on the mirror surfaces. hence, cutter can help people to cut the mirror easily and also can used it in a long term.

advantages

simple in construction
less cost
high performance
easy cutting of mirror
less time
easy operation

working principle

when the compressed air is supplied to the pneumatic cylinder and the ram extends. by means of the extension of ram, the cutter moves over the surface of the mirror and cuts it into two pieces.
