This paper researched how to substitute the cylindrical cutter with a circular cutter in the machining of the sculptured surface. The principle of the “conjugate offset surfaces of equal distance” has been applied into this field. First, suppose that there is a surface of second order, the coefficients of which are arbitrary. Then find out the best posture of the circle in order that the circle and the surface will most closely contact with each other at the origin position. Finally, develop the surface into a 3-order surface at every point of machining and employ the results mentioned above to find the best cutter posture at every point of machining. Therefore, the equations are easy to solve and clear in concept. This paper showed how to use this method for the machining of a die.
