Milling machining technology is one of the cutting-edge technology in the field of advanced manufacturing , can solve alone car or milling difficult to complete processing problems , can be the workpiece chucking completed almost all the processes , its scientific value and application prospect gradually been awareness and attention . Due to the complex movement of the milling machining , cutting parameters and these parameters are coupled to each other , so that the choice of the milling parameters become particularly complex . Has not yet been fully revealed out of the bus milling process parameters on the surface quality law, which to some extent affected the milling complex technology application and promotion . Based on cutting simulation method to study the processing parameters on the the milling machining surface roughness of law , to provide theoretical guidance for the actual processing , has important practical significance . In this thesis, ball mill, milling cutter, face milling , cylindrical cutter as the research object , through the establishment of the geometric model and processing motion model to study the surface of the milling complex micro - geometry morphology simulation algorithm and simulation algorithm the key issues emerging solution are described. Developed based on Fortran and Matlab the milling machining surface micro - geometry Topography Simulation software system , experimental verification of the validity of the simulation system developed by cutting ; then focus on the simulation system based on the development of the axial feed rate , speed ratio of the tool and the workpiece , the tool of teeth, tool angle of inclination , eccentricity , helix angle of the blade , blade angle , processing depth milling the surface roughness of the law ; Finally, a detailed study and apply simulation system based on orthogonal experiment the end mills Orthogonal milling , processing parameters affects both the milling machining surface roughness of the law , to provide theoretical guidance for the production practice .
