Curve fitting and optimal interpolation for CNC machining under confined error using quadratic B-splines

摘要: In CNC machining, fitting the polyline machining tool path with parametric curves can be used for smooth generation and data compression. this paper, an optimization problem is solved to find a quadratic B-spline curve whose Hausdorff distance given within precision. Furthermore, adopting time parameter curve, we combine usual two stages of optimal velocity planning derive one-step solution interpolation paths. Compared traditional decoupled model planning, experimental results show that our method generates smoother minimal time.
