A method for drilling holes in engineering ceramics by using a diamond tool has been developed. In this method, a drilling tool rotates with fixed abrasives. The machining mechanism of drilling based on the fracture mechanics concept is analyzed, and a ne

A tube push-bending process combining axial forces and internal pressure is introduced in this paper. The outside forces applied to the tube and the effects of the internal pressure, friction condition and push distance on the tube deformation are analyzed with mechanical analysis and experiments. Aluminum alloy tube components with a bend radius that is equal to the tube diameter were manufactured successfully in the process.
