Abstract: In order to solve the difficulty of polishing process at present. Polishing posture was analyzed at the contact spot of polishing cutter with work piece in this paper, and how to layout the polishing path and its built method were discussed emphatically, carried out simulation analysis with Mastercam software, and proposed suitable building method of path according to different region using different polishing method. Finally, it is proved that an ideal effect would be achieved.

Abstract: To achieve the structural stability of the mast of rotary drilling rig in the course of construction, analysis theory and method of FEM is applied to the study of the mast deformation of rotary drilling rig. Firstly, three-dimensional models of the mast of rotary drilling rig are created by the software of Pro/E, and then form a corresponding finite element model to carry out an analysis on the bending deformation of the mast of rotary drilling rig by the software of Ansys and to disclose the deformation regularity of the mast. The corresponding test is subsequently performed to obtain actual deformation amount of the mast of rotary drilling rig. Finally, the deformation results from the test conform to that from the software of Ansys. The method and experience of this paper will provide theoretic supports for more optimization design and research of the mast of rotary drilling rig.

Abstract: In order to improve the surface quality and machining efficiency for mold polishing. Digital automatic Polishing is a good method, MasterCAM is the software that often is used for CAM machining, path layout and building method are emphasized according to the MasterCam’s curved surface processing path setting method, and aimed at the different curved surface use different polishing path building method, at last, the rationality of the polishing path building was validated.

Abstract: The machining method and characteristic of the ultrasonic extrusion-rolling machining was introduced in the paper. According to the machining characteristic, the kinematic analysis of the machining mechanism and surface anamorphic was analyzed too. And then the correlative theory of tribology was adopted to discuss the relation between surface anamorphic quantity and the technological parameter. The theory foundation was afforded for the choice of technological parameter.
