In the free-form surface NC machining tool path generation is the key link

In CNC machining of modern manufacturing industry is one of the important contents. In the free-form surface NC machining tool path generation is a critical step because the merits of the tool path generation algorithm to a certain extent affect the final surface quality and processing efficiency. In this paper refer to a large number of relevant literature, based on the optimization of tool path  Abrasive grinding wheel  method in conducting research with several space-filling curve tool path generation algorithm. Directly generated by the algorithm have a lot of filling curves, Hilbert filling curve based on the advantages of using this curve tool path generation problem. Summed up with the matrix describing the curve in the plane forming algorithm, using matlab  polycrystalline diamond  has been different orders of the curve; build an effective algorithm, the flat surfaces in the design of Hilbert filling curve on a space vector, thereby achieve a different order of the curve on the surface of the map, is filling curve tool path generation provides a theoretical basis; this method is only suitable for rectangular area filling defects, proposed cutting plane Hilbert curve generation algorithm, also on the border complex surfaces curves of different orders can be filled, the expansion of the use of the tool path generation method scope.
