摘要
基于可拓物元模型的分析,提出了钻头磨损状态可拓评价方法。通过研究,首先设计了检测钻削力信号、声发射信号、振动信号和机床功率信号的钻头磨损检测系统,在构造经典域物元、节域物元和待评物元的基础上,通过关联函数的推演,对钻头磨损状态进行可拓评价分析,获得了客观合理的评价结果。通过与实际磨损状态比较,证明可拓评价方法具有操作简单、可靠性高和实用性强等特点。
Puts forward drill wear extension evaluation method based on the analysis of the matter-element model. Firstly a drill wear detection system is designed which is used to detect the drilling force signals, acoustic emission signals ,vibration signals and the drill machine power signals. Based on the constructing classical and sectorized field and evaluating the matter-element, through deduction the correlation functions ,the drill wear is analysed by extension evaluation and gets the objective and reasonable evaluation results. Through comparing with actual wear status, extension evaluation method has the features of simple operation, high reliability and practicability etc.
