| Abstract: | A new surface modeling approach for free-form machining is presented.On this algorithm,the surface of a part presented with a list data,is constructed with parallel mesh,to construct the mesh,the cubic spline function and parametric spline are employed to interpolate the list data points along the column line direction and row line direction,and the local spring approach to fair the curve,the mesh surface is in favor of the NC zigzag machining on the orthogonal coordinate for that the curve which is the component of the mesh surface parallel to the coordinate axes. |
