ABSTRACT:
A method of displaying on a graphic display a representation of a rotary body to be machined according to a machining program, the rotary body having a rotation axis about which the body rotates, in which an external cross-sectional shape of the body in a plane of the rotation axis is displayed in accordance with stored point data representing an external, closed line denoting the cross-sectional shape. Projected surfaces of the body and recessed surfaces of the body along the external line are represented by predetermined shading data dependent on the location of the respective surfaces with respect to the rotation axis and intervening surface lines.
