Abstract: The surface roughness of the hydraulic prop had an important effect on the wear resistance, fatigue strength and property of fit. The ultrasonic surface rolling extrusion (USRE) processing experiment was employed to improve the surface roughness of the hydraulic prop, some machine parameters such as the tools transfer magnitude, feed were studied in detail, the contact style roughness tester( Mahr S2) was used to test the surface roughness of the workpiece. The experiment results showed that the USRE could improve the surface roughness evidently, the Ra value from 0.976μm reduce to 0.105 μm by one-hit machining. The feed was linear with the surface roughness, and when the tools’ amplitude was 6.5~8.5, there were a better surface roughness Ra 0.090μm. USRE processing the surface time and again could improve the surface state.

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: 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.
