Computer controlled metal cutter

The study presents an automated oxygen-acetylene metal plate cutter entitled Computer Controlled Metal Cutter. The machine\u27s cutting path is determined by X and Y rail movements. A Z assembly decides the height of the cut. The mechanical components are driven by DC motors interfaced to a microcomputer. A feedback system using rotary shaft encoders is employed to monitor the cutting path and position of the torch at any time. Shapes of any form can be cut by the machine using the developed software capable of reading any DXF compatible file format. Control algorithms are implemented to ensure smoothness of cut and compensate for real world imperfections
