The invention discloses an omni-directional intelligent vibration damping cutting tool of a numerically-controlled machine tool. The omni-directional intelligent vibration damping cutting tool comprises a tool shank and a tool bit. One end of the tool shank is used for being connected with a tool rest. The other need of the tool shank is used for being connected with the tool bit. The side face of the tool shank is provided with piezoelectric film sensors used for detecting vibration and deformation of the tool shank. The side face of the tool shank is also provided with piezoelectric film drivers used for driving the tool shank to conduct reverse vibration and deformation according to detection signals of the piezoelectric film sensors. The piezoelectric film sensors and the piezoelectric film drivers are arranged oppositely. The omni-directional intelligent vibration damping cutting tool also comprises a controller which is in communication connection with the piezoelectric film sensors and the piezoelectric film drivers. Generated noise is low. The structure of the omni-directional intelligent vibration damping cutting tool cannot be damaged. The strength of the omni-directional intelligent vibration damping cutting tool is guaranteed. The machining precision, the machined surface roughness and the adaptability are improved, and the response frequency bandwidth and the reaction speed of vibration control are increased. The invention further discloses the numerically-controlled machine tool comprising the omni-directional intelligent vibration damping cutting tool.
Description
technical field [0001] The invention relates to the field of numerical control machining, in particular to an omnidirectional intelligent vibration-damping tool for a numerical control machine tool. In addition, the present invention also relates to a numerically controlled machine tool comprising the above-mentioned all-round intelligent vibration-damping tool. Background technique [0002] CNC machine tools are widely used in the field of machining, and they have high machining accuracy. However, in the process of ultra-precision CNC cutting, when the tool rigidity is insufficient and the overhang of the tool bar is long, vibration is easily generated, which affects the machining. Accuracy and roughness of machined surfaces shorten tool life. [0003] In the existing technology, high-strength new materials can generally be used to increase the tool quality and static stiffness to prevent chatter, but the cost is high, and the vibration damping effect of the material is po...
