基于离散点云构造径向线的螺旋加工轨迹规划方法
Spiral Machining Trajectory Planning Method Based on Discrete Point Cloud Construction of Radial Lines
摘要
Abstract
Aiming at the problems that it was difficult to directly generate efficient and accurate continuous smooth tool path trajectories based on discrete point clouds,a method to directly construct radial lines on point cloud and generate spiral machining trajectories through radial line interpolation was proposed herein.For the construction of radial lines,a boundary recognition method was pro-posed based on feature descriptors to extract boundary points as two end points of the radial lines.Taking the optimal discrete geodesics between two end points on the point cloud as the radial point set,the curvature minimization problems of discrete geodesics were proposed and solved by Newton iteration method.The B-spline curves were used to fit and resampling according to the residual height based on the radial point sets.The radial line interpolation algorithm was proposed to generate the spi-ral machining trajectory with equal residual height.Finally,an example was given to demonstrate the spiral machining trajectories directly generated by the point cloud data,which fully verified the effec-tiveness of the proposed method.关键词
