Sažetak

The basic aim of this paper is to estimate possible hazards at casting machines under high pressure in production conditions, by failure modes and effect analysis (FMEA) method. Providing high reliability, safeness and quality in the use of any technical system (TS), is a complex task for designers, engineers, technologists in the process of production and maintenance. The example, shown in the paper (casting machines under high pressure), can be used for the analysis of the reliability in the design phase and in the exploitation period of many processes in the machine industry. For this purpose an "adjusted" (simplified) procedure for failure analysis has been developed. Analysis was conducted in the production conditions in the factory FAM Secanj, Serbia. In the paper, we evaluated the failure at four casting machines by using FMEA method and by using FMEA Worksheets according to standard SRPS EN 60812:2011. Based on the RPN value (Risk Priority Number) certain corrective actions have been implemented. By application of these actions, it is possible to predict the maintenance procedures of the system in order to provide the required reliability during operation of the system.
