Abstract
AbstractEnsuring the process capability currently means the warranty, that produced products will be in accordance with requirements - from company´s side or from customer´s side. This study focuses on the statistical control of flange shaft process capability by serial production in company focused on products for automotive. The flange shaft process is evaluated by control charts, specifically by control chart for average and range (x̄, R). As the results showed, based on diagram for average and range we are able to say that the turning process is under the statistical control. Also, we had finished the reguest for capability of process, where the indexes of capability process Cpk1 and Cpk2 are higher than the determined value on 1.33 point. The normality of the measured values was verified by histogram. Obtained values are: Cpk1 = 1.645 a Cpk = 1.52. Therefore, we can consider the process as capable.
