In this study, The virtual machines instead of a common 3D measuring instrument was applied to the reverse engineering, it was investigated for the suitability. The virtual machine using reverse engineering, the intuitive model of the object was made by the designer"s eidetic skills and the NC data path and shape data generated from it. The extracted data were remodeled and approximation curve was made using NURBS curve fitting. From these series of process, the final revers engineering data of the objects could be gained.
Four conclusions were obtained from this study. First, the appropriate degree of the NURBS curve fitting is 6 degrees which has small local errors, is stable but the equation is not that complicated. Second, when it comes to approximation of curve, the radius of the curve and the increased number of the data is in inverse proportion to approximate quantity of curve. Third, in the data extraction from NC tool path, the error occur equivalent to the tool radius according to number of tool axis and direction of tool path. And accuracy of NC is more precise, and increase in the number of extracted data. Last of all, the virtual machine could extract the shape data of the object and could remodel without 3D measuring instrument, and the revers engineering was possible with only the data of 13% level of 3D measuring instrument.
