Abstract:

Aiming at the technical problems such as low stiffness, vibration and dimension error in milling thin-walled titanium alloy components, milling experiments with and without paraffin reinforcement were conducted. The acceleration signals in the milling process and the surface roughness of the finished part were measured and analyzed. It was shown that paraffin reinforcement can significantly improve  machining stability and  surface finish. The paraffin reinforcement mechanism in milling thin-walled titanium alloy component was also studied.

Key words:  , paraffin reinforcement, titantium alloy, thin-wall component, vibration, stability
