Interference Detection in Numerical Control Simulation Based on Octree Sphere Model
This paper presentes an interference detection method for workpiece and tool in numerical control machining simulation process.In this method the workpiece is presented by an octree hierarchy sphere model,and outside surfaces of the machining tool are presented by some simple curved surfaces.Using the minimum touching moment between these spheres and surfaces to detect the interference between the workpiece and the machining tool,the judgement problem of the interference in NC simulation is solved.Through this method,the interference judgment becomes convenient and effective after the octree sphere model was established.Finally,we also give an example to explain the algorithm.
