A program to simulate the process of line contact machining of revolution conic surfaces is described.

The shaping principle based on the spot-contact is presented,which can be used to fabricate any type of conic surfaces.

A fabrication technique of conic surface of revolution based on lin e-contact is presented.

According to the geometrical characteristics that the cross line of non revolution quadric surface and two groups of parallel plane in specific direction is circle,a method is studied in which the solid form of non revolution quadric surface being cut by given plane may be solved directly and accurately through drawing auxiliary spherical surface which contains the circles.

This paper studies the projections of the intersection line of quadratic cambers of revolution by combining the graphic solution and calculaton.
