| Abstract | ||||
| Accuracy in ECM is still a problem that restricts the application of this technology for accurate applications. The present investigation submits a theoretical and experimental study about shape error in the ECM process which has not been attempted before. Feed rate, applied voltage, electrolyte conductivity and initial gap size have been considered the main factors affecting the shape error value (sometimes reached 40 p1 for a 40 mm workpiece length). Experimental results have been found to agree with the estimated values with a difference less than 0.01 mm. The present results emphasize the importance of the consideration of the shape error factor for accurate tool design and shape prediction | ||||
