Abstract：[Objective]With the booming new energy vehicle industry,higher precision standards are required for automotive gears.To construct a more accurate process parameter model,a multi-process parameter optimization technology for precision gear grinding based on the Levenberg-Marquardt(L-M)algorithm was studies.[Methods]Firstly,a self-developed new form gear grinding machine was used as the test platform,and 20CrMnTi gears processed by form grinding were selected as research objects.Four characteristic process parameters were defined:grinding wheel linear speed,axial feed speed of the grinding wheel along the gear,total feed passes of the grinding tool,and single-cut grinding depth.Secondly,uniform design tests were conducted to investigate the influence of each grinding parameter on gear flank machining performance.First-order linear regression analysis was adopted to establish the functional correlation between process parameters and gear flank machining indicators.Finally,the L-M algorithm was applied with full consideration of coupling effects among various grinding factors to realize high-efficiency and high-precision machining of each grinding step.[Results]Test results indicate that the use of four optimized grinding parameters can significantly promote machining efficiency and improve the quality of machined gear flanks.
