METHOD FOR MODELDING CURVED SURFACE OF WORKPIECE USING THREE DIMENSIONAL MEASURED DATA

摘要

A method for modeling a curved surface of a workpiece by using three dimensional measurement data is provided to automatically divide measurement data having random order into a boundary point and an inner point and arrange the order of the divided boundary points. An average plane is calculated by using a reference axis from measurement points(S100). Subsequently, the measurement points are moved toward the xy plane based on the calculated reference axis(S200). An angle reference table is made by calculating peripheral points and angle(S300). Divided boundary points are arranged according to order(S600). A boundary curve is generated(S700). Next, a base curved surface is generated(S800). A corner part is restored to perform curved-surface modeling.
