The invention discloses an intelligent cutter state monitoring method based on an industrial robot milling process. The method is characterized in that in the milling process of an industrial robot, avibration exciter is installed on a workpiece to be machined, a vibration sensor is installed on the side wall of an electric spindle, the vibration exciter is used for driving the workpiece to generate constant vibration, a milling cutter makes contact with the workpiece, the vibration is conveyed to the electric spindle through the milling cutter, the vibration sensor installed on the side wallof the electric spindle collects vibration signals in real time, the collected vibration signals are different as the cutter and the surface of the workpiece to be machined are in different contact modes, and intelligent monitoring on the cutter state in the machining process is realized by utilizing the distinguishing feature. According to the method, in the process of milling the side wall of the workpiece by using the industrial robot, intelligent monitoring on the cutter state can be realized, the stability and the reliability of the technological process are improved comprehensively, andthe application and development of the industrial robot in the field of common machining are promoted.
Description
technical field [0001] The invention relates to a method for monitoring the state of a tool in the milling process of an industrial robot, and belongs to the technical field of process monitoring. Background technique [0002] Industrial robots are devices that integrate advanced technologies such as precision, flexibility, and intelligence. Today, with the continuous development of manufacturing technology, its wide application has become a trend. Industrial robots are favored due to their high flexibility and strong adaptability, gradually replacing traditional machine tools for machining parts, such as milling. Industrial robots have a larger working range and lower processing costs. Compared with traditional machine tools, their advantages are more obvious when processing large parts. [0003] In the milling process, the electric spindle is used as the end effector, driven by the industrial robot to perform feed movement according to the predetermined programmed traject...
