Development On Three Axis Cnc Machining Simulation System

NC simulation is NC machining process in virtual environment mapping. As animportant part of virtual manufacturing, it can be used to test the NC code is correct and tojudge whether there had been cut, rough cut leakage phenomenon, to shorten the productdevelopment cycle has important practical significance.Based on the analysis of the domestic and foreign existing3D simulation modelingtheory and method based on the discrete modeling technology, introduced to the NC millingsimulation modeling, put forward to include triangle based discrete modeling method forprocessing environment form construction, based on geometrical modeling method of toolpath bounding box cutter and blank intersection algorithm and based on the display list andvertex search algorithm simulation optimization algorithm in CNC milling simulation method,and the related key technologies are studied.Based on the common geometric modeling methods advantages and disadvantages, andfor three axis NC milling machining features, is proposed based on discrete modeling of threeaxis NC milling simulation modeling method. Put forward considering of effect andefficiency of three axis NC milling simulation principle, and on this basis to build three axisNC milling simulation system structure. Established for the simulation of CNC milling andcan improve the efficiency of storage and access of the blank model and tool model datastructure.
