Another approach for increasing the absorption is to turn the optical axis of HM in such a way that the direction of the resonance cone
generatrix would coincide with the normal to the HM interface [5-7].
These input parameters lead to an elliptical subreflector
generatrix with eccentricity e = 0.830880, interfocal distance 2c = 104.776381[lambda], and axial tilt angle [beta] = 172.949[degrees].
1) from the upper
generatrix to the condensate mirror (height H) it decreases from [T.sub.3] to a value [T.sub.2], and then abruptly drops to the [T.sub.1] value.
The speed vector of revolver
generatrix tangent direction is [V.sub.u] = [V.sub.a] + [V.sub.r].
where [beta] is the angle of the cone specimen
generatrix inclination; [d.sub.c] is the diameter of the cone specimen in section, where the cavity formation begins; [l.sub.cr] is the distance from the front end of the specimen to the place, in which the cavity formation begins.
To obtain an accurate description of the predominantly roughness of samples, a set of profile measurements were carried out of different sections on sample height, rotating a defined angle value for each
generatrix studied.
The constructive parameters of the workpiece and tool and also the generation ones determine the form of the directrix and
generatrix of the polygonal processed surface.
An example of the applicability of this case of composition of simple movements is the realization of the
generatrix G at the generation of the cylindrical wheel gears' flanks with cycloid profile.
The circles [C.sub.1] and [C.sub.2] can be in practice rings or disks and the
generatrix G can be rigid bars.
Considering the large industrial application, the authors have proposed the cylinder intersections study: The oblique cylinder can be modeled in four steps, by the extrusion of a circle along a line parallel to the
generatrix, followed by its upper part sectioning.
For the generating of a surface on machine tools, the
generatrix G or the director curve D are flat analytical curves (involute, ellipse, Archimedean spiral, polygonal curves, closed contour, resulting from combinations of simple flat curves, etc.) or three-dimensional curves (cylindrical helix, cone-shaped helix, combinations of these with certain flat curves, etc.).
