Abstract


Failure Mode and Effects Analysis (FMEA) is a pro-active quality tool for evaluating potential failure modes and their reasons. It helps to prioritization of the failure modes and to corrective measures for the avoidance of cataclysmic failures and improvement of the quality. In this paper, an attempt has been made to implement machinery FMEA in valves manufacturing unit of GG Valves, Udaipur, Rajasthan, India. The failure modes and their causes identifying for all CNC machines, the three key indices (Severity (S), Occurrence (O) and Detection (D)) we reassessed and the statistical analysis of failures was carried out with help of Machinery Failure Mode and Effects Analysis (MFMEA) worksheet. Finally, the necessary corrective actions were recommended.

Keywords: CNC machine failures; MFMEA; RPN; Severity; Occurrence; Detection
