Abstract : From the study of lapping machines which are bottleneck of a process flow, we found that machines’ availability is only 73 percent. Main cause came from machine breakdown due to improper maintenance strategy. Currently, a run to failure strategy is used to replace parts. This paper focuses on studying parts’ lifetimes and their maintenance and replacement costs to find out the optimal points to replace parts by using computer simulation. The result shows that changing sensor, power supply, voice coil finger, and control panel 2-months before the end of lifetime and changing motor at the end of lifetime, machine availability increases to 77 percent and net profit increases 0.38 million dollars. Keywords: Machine Availability, OEE, Productivity Improvement, Simulation.
