The closest analogue / prototype / is the invention - A device for processing paraboloids of Yu.V. Shitov according to IPC V 23 V 5/40, USSR author's certificate No. 1313561, 1987. These devices are characterized by the use of various copiers and many details that connect the cutter with the copier dynamically.

The disadvantages of the known devices include multi-element, the complexity of the settings, etc., indicated in the copyright certificates and patents.

The invention of the elliptical compass allowed Leonardo da Vinci to use the principle of his work in the invention of the machine for processing elliptical shafts, which is described in the textbooks "Analytical Geometry". This historical experience was applied in relation to another conical section - the parabola in connection with the invention of the utility model "Parabolograph", i.e. parabolic compass 06/29/2006, application No. 2006118813 with a priority of 05/30/2006, using the principle of operation of the "Parabolograph" in a device for processing proportional parabolic surfaces. The phenomenon of parabolic dynamics of rectangular plates made it possible to control the graphic element of a rectangular plate in the Parabolograph to execute a continuous line of parabolas of proportional shapes.

The purpose of the invention of the utility model is new technical and technological capabilities for precision machining by cutting, grinding and polishing parabolic surfaces of products of proportional shapes by using a rotatable rectangular plate, or part thereof, to control the movement of cutting, grinding, polishing tools.

The essence of the invented utility model is that the rotating

Around the top of the corner, a rectangular plate controls the flow of cutting, grinding, polishing tools that perform parabolic surfaces.

The utility model is illustrated by drawings, in which Fig. 1 shows a device in a static, initial position and the shape of a parabolic surface determined by the position of the pusher 7. Fig. 10 shows a device in a dynamic, final state after one of the operation cycles. Detailing with appropriate positioning is given in figure 2 - the case with a hole for fixing the top of the rectangular plate 3, the grooves of movement of the plate 4, figure 3 - a rectangular plate, figure 4 - plate, figure 5 - mounting plate cutting, grinding, polishing tools, in Fig.6 - the plunger pusher, Fig.7 - the pusher of a rectangular plate, Fig.8 - latches from the kit for the pusher 7, Fig.9 - the pusher latch 6. Position 11 shows a replaceable clamping spring in the uprights. Position 12 - helm of transverse feed of cutting, grinding, polishing tools. 13.

The operation of the device: the housing 2 is fixed to the longitudinal support, the working part of the tool 13 is mounted on the axis of rotation of the workpiece, the supply of the tool to the workpiece by the longitudinal support and the steering wheel 12 is manipulated during processing. The transition from processing convex to concave surfaces, and vice versa, is carried out by turning the housing 2 half a turn - 180 °. The distance between the centers of the pushers 6 and 7 is the unit of length of the Cartesian coordinate system in figure 1, the proportionality of the shapes of the parabolic surfaces is regulated. For example, the standard shape of a quadratic parabola and a surface formed by rotating it around the ordinate axis for a unit of length equal to 1 cm and at 2 cm the shape is doubled, at 5 cm - five times, etc.

In the process of manufacturing parabolic lenses, mirrors for optics and astronomy, diamond tools are used, for parabolic antennas - with less hardness. Optical accuracy is monitored during execution by standard tests. Practical use of workpieces with close to parabolic surfaces, for example, spherical. It is imperative that the axis of rotation of the workpiece is projected through the top of the rectangular plate of the device.
