A Novel Method for Machining Consecutive Micro Line Segments Based on Path Optimization and Interpolation Algorithm

In view of the shortages of machining consecutive micro line segments in traditional CNC systems, a novel method based on path optimization and interpolation algorithm is proposed. For achieving machining precision and high-efficiency, the original contour is reconstructed to some extent by fitting desired micro line segments into cubic NURBS curves and embedding circular arcs in sharp corners. With full consideration of machine mechanical properties, the interpolation algorithm including recursion and linear acceleration/deceleration strategy is applied to determine the interpolation points and their speed. Simulation results demonstrate that the proposed method meets the requirements of machining precision and smoothness, as well as the maximization of machining efficiency.
