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.
brackets.

6. Data Cables.
7. Lead Screws.
8. Brackets.
9. Bases to fix the motors and
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.
