High speed machining tool path generation for pockets using level sets

摘要: With the increasing application of high speed machining for pockets, conventional methods tool path generation show their limitations, such as existence a curvature region along path. This paper presents level set approach pockets. Pocket boundary is first embedded into higher dimensional function, namely, function. Then paths are realised by propagation pocket boundary. The topological changes can be naturally handled during evolution moving fronts. In order to avoid appearance corners paths, curvature-dependent term adopted regulate velocity function equation. At same time, flow motion used identify machinable vector level-set functions utilised handle complex pockets with multiple islands. simulation material removal rate based on implici...
