Finite element analysis-based vibration analysis and suppression of CNC tooling

In the modern manufacturing industry, computer numerical control (CNC) is widely used because of its high precision and high efficiency processing ability. Tool vibration is a common and serious problem in CNC machining process, which affects machining accuracy and surface quality. In order to solve this problem, based on the finite element analysis (FEA) method, this paper makes an in-depth study on the vibration of CNC tools, simulates the dynamic response of tools under various working conditions by constructing FEA model, and identifies the key vibration mode and natural frequency of tools through this model. The experimental results show that without suppression, the vibration amplitude of the tool reaches 1.3 mm at high frequency. By introducing integrated damping material and adaptive control algorithm, the vibration suppression rate can reach 48%. This shows that this method has significant advantages in reducing vibration amplitude, improving machining accuracy and prolonging tool life, and provides a comprehensive and effective solution for vibration suppression in CNC machining.
