【Abstract】 This paper discusses the source of movement error in gear hobbing process, and it is established a mathematical model for description of the error rule. The least square parameter estimation is adopted, and the nonlinear problem of the mathematical model is solved. Two methods of error sampling and error compensation in the process of gear hobbing are given. The simulation and practice application show that the compensation method is efficient and practicable.更多还原
