A milling machine is an essential machine tool in practical laboratory activities due to its ability to produce components with high precision. However, excessive use and aging of the machine can lead to failures that reduce its performance and disrupt learning activities. This study was conducted to analyze and identify the root causes of failures in the mechanical and electrical systems of the Aciera F3 milling machine using the 5 Whys approach. The research methodology involved direct observation, interviews with technicians, visual inspections, and electrical testing using a multimeter and test pen. The 5 Whys method is a root cause analysis technique that identifies the underlying causes of a problem by repeatedly asking the question "why" until the fundamental cause is determined. This approach helps reveal the relationship between observed symptoms and their actual causes, enabling appropriate corrective actions to be established. The results indicate that the 5 Whys method is effective in supporting the identification of root causes and the development of suitable corrective maintenance measures. After the corrective actions were implemented, the system was able to operate normally again, and the machine could be used according to operational standards.
