The problem in Sheet metal spinning is limited to an axisymmetric part. This research aims to design and build a flexible mechanism by a combination of mechanical with the electrical system to achieve the forming of polygon spun parts with a different number of sides without using a specific mandrel. This system based on developing a synchronous spinning machine, in which the rotational motion and feeding of the tradition lathe machine were measured and control to maintain the speed synchronization with the trajectory of the forming tool rollers (a special tool of forming), where this tool controlled by the electrical motors. The speed of the electric motor controlled by variable frequency drives VFD, pulse-controlled, and software. The machine can be applied to produce several shapes by changing pulse-controlled inside software code, which means that’s the machine is much more flexible than any other way. In this survey three spun parts (triangle, square and hexagonal) cross-section parts were produced, and aluminum alloy sheets (1050) of circular shape with 1.5 mm in thickness and 150 mm diameter will be used in this process. Finally, the output from this process will compare with a CAD model to examine the process validity by comparing the dimensional accuracy. The result shows that the average dimensional accuracy error for the triangle, rectangular, and hexagonal spun parts are 14.15, 6.47, and 3.78 respectively which consider an acceptable percentage in the spinning process.
