Failure Mode and Effects Analysis in the Repair of Infantry Rifles: An Application Using the Taguchi Approach

Abstract

Visual inspection methods are commonly used in the repair of infantry rifles. Consequently, personnel failures, the use of inappropriate methods and materials, as well as labor and time losses may occur during the repair process. The absence of a standard procedure for repair activities negatively impacts reliability and continuity. Failure Mode and Effects Analysis (FMEA) is a technique used to identify potential failure types and assess their effects by examining the entire system, design, or process. In this study, the repair process of infantry rifles was analyzed to identify potential failures and to determine the precautions. Eleven failure modes that may occur during the process, such as improper storage, improper coating, inadequate lubrication after repair, and neglect of control steps, were focused on. A cause-and-effect diagram was used to identify the root causes of failures that require absolute prevention. In order to determine the appropriate coating thickness for the “improper coating” failure mode with the highest Risk Priority Number, the Taguchi method was utilized by determining the relevant parameters and levels. As a result of the analysis, it was found that the most effective parameter for the coating thickness was the chemical ratio, with a delta value of 5.94. The optimum coating thickness of 9.04µm was obtained under the conditions of 90 ℃ temperature, 20 minutes treatment time, and 20% chemical ratio.
