Следы вибрации при обработке на станках с ЧПУ часто вызваны различными факторами.. Вот некоторые возможные решения:
- Reduce the weight of the part causing vibration, minimizing inertia.
- Fix or clamp the areas where vibration is greatest, such as with a steady rest or workholder.

- Increase the rigidity of the machining system, such as using a toolholder with a higher spring rate or a special vibration damper with a dynamic damper to absorb impact energy.
- Address the blade and workpiece rotation direction, such as by changing the tool shape and lead angle to reduce cutting resistance.
- Check whether the machine speed fluctuates significantly. If so, try switching from rotary feed to fractional feed.
- Consider the workpiece itself or the workpiece’s rigidity. Например, some smaller, thinner parts may lack rigidity or their shape may prevent adequate clamping using a suitable press-fit fixture.
- Check the tool for issues, such as excessive tip radius or excessively wide blades. You can simply sharpen the tool by hand to reduce vibration.
- The selection of cutting parameters is also crucial, including cutting speed, кормить, feed amount, and cooling method.
В итоге
Solving the chatter mark problem requires comprehensive consideration of multiple factors such as machine tools, режущие инструменты, заготовки, cutting parameters, и т. д.. By adjusting and optimizing these factors, vibration and chatter marks can be effectively reduced, and processing quality and efficiency can be improved.
