The transmitter trajectory is determined by the intersection line formed by [L.sub.T] and the

conical surface. If the transmitter moves with a fixed altitude, [L.sub.T] is parallel with the ground plane, which leads to a hyperbola trajectory as shown in Figure 5.

The last software tool proposed in this paper refers to the utilisation of a secondary optics in the furnace: in particular Simulation Tool_3 (ST_3) allows introducing a polar

conical surface as secondary optics of the collection system.

Because of the fact the intersection is both the spherical and conical locus we can indicate the identically equivalent circle of the spherical one on the flattened

conical surface but of different properties e.g.

Then again checking-up of quality of conical bottom follows so that the

conical surface would not be damaged in any place.

A CNC3[n] nanocones consists of a triangle as its core and encompassing the layers of hexagons on its

conical surface. If there are n layers of hexagons on the

conical surface around triangle, then we number n denotes the number of layers of hexagons and number in the subscript shows the sides of polygon which acts as the core of nanocones.

The flight trajectory intersected by plane y = [y.sub.0] and

conical surface forms an ellipse as analyzed in Appendix A.

* InspF Cylindrical or

conical surface represents a product mating where just feature own geometry participates in the functional chain.

The tool moves by oscillating motion in direction parallel with the axis of this cylindrical surface that can cause the damage of the created

conical surface even before the superfinishing.

The current point coordinates of the curve placed on the truncated

conical surface, A(x,y,[z.sub.A]) may be deduced using the Fig.3 and the following relations:
