A precise solving method for helical groove process based on an improved NSGA-II algorithm
摘要
The helical groove geometry parameters are essential factors for ensuring tool performance. The precise manufacture of tools with different tool performances based on the existing grinding wheels in the grinding wheel library is a pressing problem that needs to be addressed in the modern tool manufacturing industry. To address this issue, a solution method for helical groove grinding process parameters based on existing grinding wheel libraries was proposed. Combining spatial analytic geometry and conjugate surface theory, a kinematic model of the helical groove grinding process was established, and an improved NSGA-II algorithm was used to solve the grinding process. Finally, numerical examples were presented to demonstrate the validity of the developed model and algorithms, and the numerical results were verified through the dynamics simulation of UG. The results indicate that the methodology proposed in this paper enables accurately solving the grinding process of helical grooves that cater to various machining performance demands.
