Sažetak
Results of accuracy tests presented in this paper were obtained during the control of dimension of the cover of the second stage pressure regulator on breathing mask that is made of stainless austenitic chromium-nickel steel WNr. 1.4301 0, 6 mm thick, with deep drawing process.The analysis of the mechanical properties and thickness of material assume the appearance of dimensional inaccuracies due to elastic spring recovery. The process of deep drawing which forms a roundel to the demanded geometry is realized in several operations which result in a cumulatively greater elastic spring recovery. The greater the extent of such discrepancies resolved by redesigning of product and introducing two additional phases aimed to draw reinforcements. Test results confirm that deviations appear even after the redesign 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.
