Testing of processing route of tungsten alloy balls;

A study on the optimization of a processing route in numerical control turning;

This paper discusses the definition of nearest processing route in the processing of numerical controlled machine tool and reaches a conclusion that how we can get shortest route for empty processing.

Multi-holes machining path optimization based on dynamic algorithms;

This paper presents the technical requirement machining of numerically controlled engine lathe,and analyzes the principle of the procedure dividing in the machining,and illustrates the principle of how to confirm the machining path.

The technology of line reinforced by the temporary beam in the D pattern and container bridge jacking has been widely applied.

Taking the reinforced concrete frame overpass of Longhai Railway and Xikang Railway under-passing Hedi East Road,Baqiao District,Xi an City,as an example,this paper sums up some critical procedures such as the line consolidation and jacking construction and some measures for security in the jacking construction technology for existing railway under-passing the Large-frame bridge.
