This research aims to study the reduction of losses incurred from cutter failures, which is the main machine to cut the final parts before packing, in the process of cutting chicken parts. There is no replacement for the engine when it fails, and this has a significant impact on the cutting process of chicken parts.
The researcher conducted a factory study before adjusting the O.E.E. value to reduce the loss by applying the technique of analyzing the machine's overall effectiveness to be applied together with the Why analysis, which is a technique to search for problems or select topics. Setting goals for research planning, finding the cause of the loss, considering ways to improve, and setting control measures from the collection of data, it was found that the machines had frequent breakdowns and intermittent interruptions that accumulated, affecting the target of daily production. From the examination, it was revealed that three main reasons caused this problem: Servo Motor Alarm, Emergency Switch Alarm, and Proximity Sensor Alarm. Such situations were solved by checking and sharpening the cutting blades regularly. Each day’s work included covering the emergency button while cleaning the machine and replacing the spare parts at the specified intervals. The average overall productivity of the cutter was 70.02% higher than before the improvement and 88.70% after the modification, an increase of 18.68%.
