摘要
ABSTRACTVibratory finishing within restricted space is an effective way to finish the surface of complex cavities in an aero-engine integral casting casing, where the contact mechanism between the processing media and the rough surface is the nature for producing the processing effect. In this work, vibratory finishing was performed by semi-shading the workpiece, comparing the workpiece surface profile change with time for different vibration directions and processing positions, and height parameters and feature parameters evaluated the rough surface. The results show that the process of profile change on the workpiece mainly subjected to normal action is mainly the raising of valleys after profile peaks extrusion deformation and accompanied by the formation of finer peak-to-valleys. The workpiece subjected to tangential action reduces the surface roughness by filling the valleys after cutting the peak tips. The finishing mechanisms for rough surfaces can be summarized as collision, roll-pressing, and scratching.KEYWORDS: Vibratoryfinishingmechanismprofilepeaksvalleycollisionroll-pressingscratching Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThe work was co-supported by the National Natural Science Foundation of China (Grant No. 52075362 and 51975399) and the Shanxi Province Graduate Education Innovation Project (Grant No. 2022Y165).
