Research paper on sheet metal cutting. Sheet metal is simply a metal formed into thin and flat pieces. In shearing operation the pressure exerted by the punch causes the plastic deformation of the sheet metal. It is used to cut and bend the small size of the sheet metal. Consequently the objective of this paper was to design and analyzed a multipurpose sheet metal machine to improve the production of sheet metal process and enhance competitiveness of the sector.

A gillotine paper cutter would probably do real thin sheet metal like litho plate or aluminum but kinda upside down and inside out way of doing it. This paper discusses in detail the design and implementation of such a low cost automatic metal sheet cutting machine. In terms of computational complexity the problem is an np hard problem reducible to the. Introduction the sheet cutting machine is the heart of sheet metal.

In operations research the cutting stock problem is the problem of cutting standard sized pieces of stock material such as paper rolls or sheet metal into pieces of specified sizes while minimizing material wasted it is an optimization problem in mathematics that arises from applications in industry. It can be replaced by a pneumatic cutting machine which cancut the sheet metal at a faster rate and in a convenient way 5. It is one of the fundamental forms used in metal working and can be cut and bent into a variety of different shapes. The compressed air from the compressor is used as the force medium for this.

Sheet cutters are used which requires human effort to cut down the sheets. Force required to cut the sheet l t tmax for sheet 10 mm thickness force required 25 10 30 7500n this is the force required to cut the sheet metal however the initial force required to cut the sheet is more and it is 140 150 than we calculated therefore max force required to cut the sheet 10500 11250 n. The machine is portable in size so easy transportable. The sheet metal cutting and bending machine works with the help of pneumatic double acting cylinder.

A pneumatic system for sheet metal cutting in a easy manner. The main advantage of pneumatic sheet metal cutting machine is to improve product quality repetition of work and increasing production rate. Design and fabrication of pneumatic sheet metal cutting and bending machine.
