Abstract


Modern manufacturing techniques evolving towards intelligent direction, whichhas made the simulation of process become an important feature of modern CNCmachining technology. However, due to the limit of mechanical and the complexityof the interaction between power and heat, the processing of the physical simulationis very difficult. And the surface morphology determines the quality of thework-piece, has a great impact on the reliability and service life of the work-piece.Thus, study on the surface morphology of in-depth has very important significance.Tracking domestic and overseas manufacturing cutting-edge virtual simulationtechnology research for ball mill, taking full account of the machining parameters onthe cutting edge micro-element for the study, using space matrix transformation, therigid trajectory model of infinitesimal cutting edge relative to the work-piece havebeen established. Based on this, surface topography prediction model, comprising thethermal of tool and work-piece, tool force, vibration, wear information, have beenpresented. Using displacement vector of infinitesimal cutting edge under multiplephysical factors to correct rigid trajectory, a model with considering more physicalfactors have been established. Using MATLAB as mathematical software, tocalculate theory spatial displacement law of tool and work-piece, basing on spatialtrajectories of edge micro-element, surface morphology simulation results can beobtained. Basing on the simulation results, surface roughness can be predicted. UsingVisual C++6.0as a software development platform, a comprehensive ball millingsurface topography simulation model can be established.The prediction model of surface topography has been proved to be effective andreliability by an experiment. The method has a good guide to improve processingquality and production efficiency.
