To generate axisymmetric aspheric surface function rapidly, virtual quadratic curves are adopted. Mesne constant, peak to picked length L, half parietal angle alpha and inclination between section & axes Phi are adopted in the selection of suited curves. The relationship between L, a, Phi and idiocratic parameter p, eccentricity e is analyzed with Matlab. Then machining locus is generated and optimized. Research results showed that, with the mathematical model found on the basis of virtual quadratic curves, the axisymmetric aspheric function and its machining locus could be generated rapidly.
