In recent years, industrial goods and consumer products, for example, telephones and cameras, have been made of three-dimensional free form surfaces. The free form surfaces should be comfortable at the interface between human and machine. It is predicted that the elaborate design will become principal parts of the products. This paper deals with a new method for extracting features from the three-dimensional object with free form surfaces. The method deals with extracting a form feature from a convex hull of the object and machining features from the object's concavity. The convex hull is calculated by means of an outermost point method and expanded in a series of spherical functions. The concave areas are characterized by diameters and directions of tools which remove the concave areas during machining processes.
