The cold plastic working continue to develop compared to machining by molding or hot deformation. A number of advantages, both technical and economic, can be obtained by the plastic deformation. The experimental researches were carried out for three materials: aluminum, brass and copper. There are presented the influence of the number of whirls, of the discharge energy and of the discharge voltage on the deviation from the height of the part for different thicknesses of the sample. In case of aluminum there is a significant decrease of the deviation from height if the sample is of 0.15 mm thickness and a reduced decrease when using material with a thickness higher than 0.15 mm. When the brass material was used the increase of discharge energy leads to a significant decrease in height deviation of the parts. At different values of discharge energy the increase of the number of whirls leads to the almost comparable decreases of the deviation when the thickness was 0.15 mm and 0.5 mm. In the case of copper the increase of the discharge energy leads to the decrease of height deviation of the part with comparable values for the two thicknesses of the used material. The same observation can be drawn in case of the influence of the number of whirls on the deviation from the part’s height. |
