Description
Summary:The operating state of motorized spindle directly affects the machine tool performance, and the evaluation model of operating state was proposed in this paper to improve the stability and reliability of the motorized spindle. The composite index was introduced based on multi-characteristic parameter evaluation model to quantitatively characterize the operating state. The statistical analysis method was used to classify the operating state data that matching the evaluation grade of the motorized spindle. The experimental results proved that the evaluation model can be used to classify the running status of the motorized spindle based on the composite index, and the index could provide references for tracing back the deterioration factor. The proposed operating state evaluation model could provide theoretical support for rational arrangement of maintenance and shorten maintenance time.
