This paper shows a deep study of highly characterized and relatively small size B3 spline curve,which is based on a through comparison among various key technologies used in reverse engineeringthe fitting methods of curve and surface,then this theory is used to work out arithmetic for interpolation of B3 spline curve,for its successful application of high precision cam reverse design.

The arithmetic of curves and surfaces reconstruction in reverse design of high-speed cam based on B3 spline is researched,and the mathematic model is built.

A transformed B 3 spline function was used to simulate the warping displacements along the cross section of the thin walled members.

The Approximation from Ellipse and Spline to Polyline In Estate Surveying;

It analyzed the application of Curve-Surface Modeling Technology in CAD/CAM,and described the characteristics of polyline and spline in AutoCAD.

According to the unwrap curves equation of the intersection of cylinder vessels opening for nozzles,smooth template curves for both opening and nozzle are plotted with the aid of cubic splines.
