Abstract:

One of the most important non conventional cutting methods is Plasma Arc cutting. It is highly accurate, good surface finish, and having ability to cut any hard materials. Plasma cutting can be used to cut all electrically conductive materials, such as structural steels, high-alloy steels; nonferrous metals i.e. aluminium and copper. By using plasma cutting technology, sheet metal between 0.5 mm and 180 mm thickness can be cut. For cutting of sheet metal, plasma cutting machine is used. In plasma cutting machine, three pairs of rack and pinion gear are used to obtain motion in the X and Y direction. In this system, torch to work distance is manually adjusted. In this conventional system, Bevel cutting of metal is not possible. Setting of angular motion of torch is not possible in conventional cutting method. In this study, special mechanism is designed for vertical and angular motion of torch, i.e. oblique to the cutting surface of torch for bevel cutting. Model of this mechanism is developed using CATIA. Bevel cutting up to 50 degree is achieved by using this mechanism. The results are validated experimentally on a torch head Mechanism model manufactured. Stress analysis of mechanism is carried out by using suitable CAE software.
