Beschreibung
Zusammenfassung:	A three dimensional surface shaping tool comprising a machining portion, wherein a graphical projection of the outermost locus of the motion of the machining portion, onto a plane parallel to the longitudinal axis of the tool, has a shape comprising a curve expressed by at least one equation or a combination of at least one straight line and at least one of the curve, and a three dimensional surface shaping method using the above mentioned tool, which comprises the steps of determining the desired shape of the surface; choosing a shape of the tool based on the desired shape of the surface; and contacting the tool with a workpiece under tool motion control such that the contact with the tool occurs at points along the machining portion of the tool where a curvature thereof is most appropriate for the desired surface shape.
