Synthesis of design solutions based decomposition of object

The easy way for recognize object display of the drawing.

            My dissertation: "Synthesis of design solutions based decomposition of object"

                I want to share with you my idea that I realized in the 90s, it was thirty years ago. It was the best technique for recognizing the geometric shapes of drawings, which was used for the automated writing of technological processes. This method was used to create an automated system for technological preparation of production (ASTPP).

                I will try to disclose the secret of my work, which you can use in the Mechanical AutoCAD. Of course, I cannot reflect my entire dissertation here; however I can explain the essence of the process. In my work, I have tried to reflect the actual human thought process. Namely, how a specialist makes a decision, which knowledge he use. Why he to make choose exactly this decision?

                The analysis of this process showed its logic, which was used in the system operation algorithm.               For example, you are drawing a line on your computer; the computer takes this as two points and the distance between them. But when you enter a dimension symbol, dimension line with symbol such as diameter or radius, the computer takes that line as a surface, a body of revolution, dimension without symbol - it will be a flat surface. Except symbols dimension line have size with tolerances.  And if this line additionally contains a symbol of quality, you understand, and the computer also, that this surface, a body of revolution of such quality and size with tolerances can be obtained by such methods on such equipment and of such tools.

                How did you know about that? As a specialist, you have already accumulated certain knowledge, experience, used reference books - and all this constitutes a certain base of your knowledge. All this characterizes the surface and determines the method it is processed.

                Thus, we approached the need to create a unified Knowledge Base (KB) that does not depend on real manufacturers and factories.

                In this unified Knowledge Base, we store all kinds of quality assurance methods for a specific element of an object, that is, a part. According to a certain algorithm, we first select a set of knowledge for each element, and then (collecting) unify them for all elements, that mean provide synthesis of design solutions based on decomposition of elements of object.

                Following our logic, according to a certain algorithm, the remaining unified solutions are compared with the Database (DB) of a particular enterprise and the found data are entered into the technological process. In the absence of the necessary tools, fixtures or equipment, an order is made for their acquisition or creation and manufacture.

                Thus, in addition to the Knowledge Base, it is now necessary to access the Database. The interface between the bases allows you to mutually replenish them with information.

                Of course, this is very simplistic, in the process of developing the algorithm of the automated system; other important factors were used, such as the approach, accessibility to the surface, as well as the choice of the reference axis or reference surface. But all this does not pose a problem if you use the rule according to which all surfaces in the drawing have size, tolerance, quality and strength characteristics, and are also marked (base axis or surface).

                I would like to draw your attention to an important point; we used a little different from AutoCAD graphic system - "Compass-5".

This is analogous to AutoCAD, only each symbol in the drawing has a link to the program file (inside the Compass). So, for example, for each class of surface purity, accuracy class, strength characteristics of the material (by type), and the system had its own code by which access to the Knowledge Base took place.

                After all, it is very simple, reliable and without the need for highly qualified specialists to intervene in the process of creating a technological process.

                With the use of such a system, thousands of technological processes were developed in the Soviet Union at various enterprises of the defense industry.

This was Stanetsky's methodology, that is, mine.

                This system was created by mechanical engineer Anatoly Stanetsky at the Temp plant in the city of Khmelnitsky under the leadership of Academician, Professor, Doctor of Sciences Vladimir Ostafiev (Kiev Polytechnic University).

It's simple, reliable, and easy to apply to any enterprise. Does not depend on the enterprises, they fill the Database themselves.
A similar logic was used to design technological tools, dies, and molds.
