| Abstract | ||
| Occasionally, the state organizations and many private companies in Thi Qar Governorate request some spare parts that must be manufactured locally because they are unavailable in Iraq .Since these parts have complex shapes, and the Engineering College Workshop's machines are unable to cut them, thus it was necessary to develop the existing Oxy Estelline cutting machine to control its motion by computer. The main idea of this research is to make the machine cutter movement in two dimensions according to a path drawn by (Autodesk Land Desktop) program which necessitates addition of an electric circuit (Interface) between the machine and the computer to convert the path into two dimensional motions .This requires replacement of some unnecessary parts from the machine by others. The major added parts are: 1. Servo Motors. 2. Controller. 3. Drive. 4. Power Supply. 5. Power Cables. 6. Data Cables. 7. Lead Screws. 8. Brackets. 9. Bases to fix the motors and brackets. After welding processes of the bases and mounting the motors, brackets, and electric circuits, the machine was tested by fixing a pen instead of the cutter and drawing many graphs such as circle, rose, gear, and gasket on a paper .The drawings are completed successfully and accurately, then the machine was used to cut rose and gasket by the flame .Satisfactory results are obtained .Now, the user can use the machine easily to cut any complex shape. | ||
