摘要
BTA深孔钻是一种典型的深孔加工内排屑钻头,加工用量大加工过程封闭。针对工业现场BTA深孔钻磨损人工检测误差大的不足,基于最小外接矩形的磨损视觉检测方法对BTA深孔钻的磨损进行了检测。通过对刀具磨损图像进行图像预处理,包括图像的灰度化、滤波去噪处理以及阈值分割,得到了清晰的磨损区域图像。将预处理图像应用最小外接矩形方法得到刀具的磨损量,分析了磨损量对加工孔径的影响。采用上述检测方法对BTA深孔钻进行了试验分析,为提高刀具的使用寿命提供数据支持。
BAT deep-hole drill is a typical inner-chip removal drill,which is processed in a large amount and the machining process is closed. In view of the deficiency of the industrial field BTA deep hole drilling wear artificial detection error,the wear of BTA deep hole drilling was detected based on the wear visual inspection method of the minimum external rectangle. First,getting a clear image of the wear area through the tool wear image preprocessing which include image gray,filter denoising and threshold segmentation; Then the tool wear was obtained by using the minimum external rectangle method in the preprocessed image,and the effect of the wear rate on the processing aperture was analyzed; The above detection method is used to test the BTA deep hole drilling,which provides data support for improving the service life of the tool.
