RT Journal Article SR Electronic A1 Kalincová, Daniela A1 Ťavodová, Miroslava A1 Čierna, Helena T1 Root Cause Analysis for Identifying Defects in the Process of Cylinder Head Castings from Aluminium Alloy JF Manufacturing Technology Journal YR 2015 VO 15 IS 4 SP 546 OP 553 DO 10.21062/ujep/x.2015/a/1213-2489/MT/15/4/546 UL https://journalmt.com/artkey/mft-201504-0010.php AB The research into root causes of defects in cylinder head castings are described in the paper. Chemical composition of castings, evaluation of casting microstructure before and after the heat treatment and final inspection of casting quality from various points of view are parts of the research. The list of the most common defects in case of using five selected products is the result of the experiment. The objective of the research was to identify causes of defects in the process of cylinder head casting as well as to identify root causes of discrepancy using the quality management tool.
