Control of dimensional accuracy in deep drawing process with more phases

The process of deep drawing is realized in several operations which result in acumulatively greater elastic spring recovery. The final product was redesigned and two additional phases aimed to draw reinforcements were introducing. Test results confirm that deviation sap pear even after there design and as a consequence of the tool wear on functional area. Based on the identified discrepancies in the products and subsequent control of the tool, it was concluded that it is necessary to correct it with grinding.
