OEE analysis and preventive maintenance for compressor blade machining unit equipment
Through the overall equipment effectiveness analysis of the compressor blade machining unit,it is found that there is a large time loss in the performance start-up phase.To address this issue,a preventive main-tenance strategy is proposed,and the calculation model of total preventive maintenance cost is established based on the related cost caused by maintenance,service age regression factor and equipment operating cycle.This model is optimized using a genetic algorithm,yielding the lowest cost solution.The model is tested on the exam-ple of 550 hours equipment operating hours,and it is found that 6 preventive maintenance times are the most rea-sonable.
