INTRODUCTION


Toolpah generation and optimization is considered as a challenging problem in the academic and industrial communities. The objective of this project is to minimize the cost of toolpath based on curvature and engagement metrics. A novel approach of toolpath generation and optimization is proposed. The quintic spline is used to approximate the original toolpath. Some important metrics are modeled based on the physical requirements. An iterative optimization  approach based on graphics simulation is proposed to improve the toolpath. Case studies show the validity of this approach. Software is developed for this application.
