The equation of identical slope gradient surface could be constructed expediently when the exact expression of lead curve is known.But in practical engineering,the exact expression of lead curve is hard to obtain;and only some measured data points are given.For solving that problem,a method of constructing the identical slope gradient surface in engineering is presented.Firstly,cubic parametric interpolation curve with second order continuous is constructed according as the measured data points,which is regarded as the lead curve.Then,the parametric equation of identical slope gradient surface is constructed based on the forming principle of that surface,which forms the basis for computer aided geometric design of identical slope gradient surface.Lastly,some examples are given to show that the method is feasible and effectual,which accord with the practical engineering.
