1. A machine tool evaluation method using at least one target component of a machine tool, comprising:
acquiring type information and attribute information of the at least one target component;
acquiring, based on the acquired type information and attribute information, target operating condition data, target state monitoring data, and target design parameter data corresponding to the target component;
providing an original data set based on the target operating condition data, the target state monitoring data and the target design parameter data;
transforming the original data set to obtain a target data set based on a target preprocessing rule matching the type information and the attribute information of the target component;
extracting features of the target data set to obtain a feature data set based on a target feature extraction rule matching the type information and the attribute information of the target component;
executing a multi-level evaluation on the target component based on the feature data set of the target component and providing a multi-level evaluation rule matching the type information and the attribute information of the target component, the multi-level evaluation rule being configured to provide an evaluation result of the target component;
establishing an evaluation result of the machine tool based on evaluation results of the at least one target component; and
optimizing the machine tool based on the evaluation result of the machine tool.
