摘要

A novel vibratory thru-feed rolling process for involute splined shafts was introduced and experimentally validated. The effects of lubricating medium, vibration frequency, and vibration amplitude on rolling torque were investigated and analyzed. Through experimental analysis and the use of a non-linear surface fit method, optimum process parameters were determined as 40 Hz for frequency and 0.5 mm for amplitude under oil lubrication. An additional experimental validation under these optimum conditions showed that rolling torque was reduced by 26.14%, providing a further decrease of 12.45% compared to the best results obtained without vibration. Moreover, the dimensional precision and mechanical performance remained within the specified requirements. In particular, the grain size underwent a refinement of 50.75%, residual compressive stress was improved by 145.44%, and hardness increased by 30.22%.
