Research on slicing algorithm of worn components model in flexible remanufacturing based on welding robot

This paper deeply researched on slicing algorithm of worn components model,aiming at the remanufacturing of worn components model based on slicing and accumulating method of welding robot.Consider the diversity and random of worn components,An arbitrary plane was taken to cut STL model.Direct slicing method was used in order to save the time of building topology information and the triangles array.First of all,an algorithm for intersection between an arbitrary plane and STL model was derived.Secondly,all the intersection points were fit to the section contour using cubic B-spline after queuing intersecting points of each layer.Finally,the algorithm was realized based on VC++6.0 and Open GL.One typical slicing example was given to prove the algorithm's accuracy,providing a basis for the path plan in flexible remanufacturing based on welding robot.
