摘要
针对数控机床加工环境,就如何快速定量检测刀具磨损状况的问题,开发在机环境下的机器视觉检测装置。根据图像灰度分布区域差异性特点,提出基于8连通邻域搜索的交互式刀具磨损提取算法。实验结果表明:该检测方案误差可控制在5%范围内,能够满足机械加工的要求。
Considering the environment of CNC machining, the authors proposed a method for detecting tool wear condition rapidly and quantitatively in this paper. Firstly,considering the CNC machine tools processing environment, they designed an intelligent visual detection device in the machine environment. Then, according to the characteristics of the image gray distribution of regional differences,an interactive algorithm based on 8 connectivity neighborhood search of tool wears was proposed. Experimental results show the program error is in the range of 5%. The result indicates this method is able to meet the requirements of the machining.
