Abstract

The lathe machine is a flexible and often used tool in manufacturing and machining. It is essential for accurately and effectively shaping and machining a variety of workpieces. In FTKIP laboratory, lathe machines are frequently use for different processes with different parameters. If maintenance is neglected, it can affect the machine functionality and the safety of the machine user. This study was developed with the purpose of enhancing the lathe machine functionality by recommending OPL and SOP for abnormalities elimination for the machines. The main objective was to study and apply the best autonomous maintenance practices for abnormalities in lathe machine at FTKIP laboratory. Fuguai analysis was carried out to find abnormalities on the lathe machine. During the machine inspection, any fuguai found is marked with F-tag, meaning it required attention and further actions. The implementation of several One Point Lesson (OPL) and Standard Operating Procedure (SOP) has been carried out to eliminate the abnormalities found in the machine. This project only focuses in implementation of autonomous maintenance practices on lathe machines in FTKIP laboratory. It does not include other maintenance strategies like preventive and predictive maintenance or broader organizational changes beyond the autonomous maintenance framework within the specified manufacturing facility. This research identified that the most fuguai found are in physical category which is can be done by the machine user and operator. Different OPL and SOP for fuguai elimination is created for better guidance to the machine user. Some of fuguai cannot be eliminated since it required an expert technician. This type of fuguai is marked with red F-tag. The standardisation of OPL and SOP of a machine are crucial since it is the main guidance for the machine user in autonomous maintenance activity. Implementation of basic steps of autonomous maintenance play important roles in sustaining the machine efficiency. This project can encourage the students in FTKIP to apply autonomous maintenance when using machine in laboratory.
