AI Technical Summary
⚠Technical Problem
In computer numerical control (CNC) machining, machine tool vibration is transmitted to the fixture system through rigid connections, resulting in coupled vibration between the fixture and the workpiece, which affects machining accuracy and surface quality.
⚗Method used
The fixture employs a honeycomb panel, shock absorber, and compression spring structure. The honeycomb panel initially weakens the vibration, while the shock absorber and compression spring further weaken and buffer the vibration, thereby improving the anti-vibration effect of the fixture.
🎯Benefits of technology
It effectively reduces the impact of vibration on machining accuracy, improves the performance of fixtures and the machining accuracy of workpieces.
