Abstract

The titanium alloy thin-walled parts with rotary structure are often used as the elements for positioning, connecting and load bearing in aerospace field. However, tool wear will appear in the precision turning of such parts by using cemented carbide tools or diamond tools, and the machining accuracy deteriorates. On basis of the study on machining features of titanium alloy thin-walled parts with rotary structure, the cutting error is corrected for tool wear by online compensation, and the machining deformation caused by cutting force is controlled by using diamond turning with ultrasonic vibration in this paper. The elliptical ultrasonic turning is used to machining a typical spaceborne titanium alloy thin-walled cylinder with minimum wall thickness of 3mm, and the roundness error is controlled to 2.83μm for the machined inner hole. The requirement is satisfied on shape accuracy, and the machining feasibility is proved.
