摘要:
Abstract:
 Regarding the requirements on monitoring the cutting tool edge during ultramachining, a study of cutting tool monitoring method based on shape matching has been launched. A tool image acquisition system, which combines improved Brenner gradient operator and control system of machine, was designed and established to achieve the autofocus function of cutting tools. On the premise of making sure the image focus accuracy, the improved Canny operator was adopted to calculate the edge point position as well as gradient direction vector. Then the initial and obtained images were compared to judge whether the abrasion tool is worn. Experimental results show that the monitoring result of the system has a strong correlation with flank wear VB, and has the advantages of great stability and high efficiency. So the score of the shape matching can be the judgment for the tool wear.
