Structural Design of Configured Patterns of Avionics Parts 38_13.pdf

The paper presents a set of means for structural designing the configured patterns of avionics parts. The specificity of the offered approach to designing this kind of an equipment is defined with the use of means of conceptual experimenting. Such type of experimenting suggests a reflection of the life cycle of any pattern to a semantic memory of the question-answer type. The structure and attributes of the semantic memory cells are focused on coding of models of questions and answers from the viewpoint of their use in solving the creative tasks. In such modeling, any conceptual experiment is conducted as automated mental experiment the structure and content of which are operatively used in designing of patterns.Configured patterns as a specialized equipment for manufacturing and checking of avionics parts have a set of features the main of which are the following: complicated geometrical forms, small rigidity, greater scales, strict requirements to accuracy of manufacturing. Moreover, in the creation of each pattern, it should repeat not only the geometrical forms of the corresponding detail, but needed utility forms should be included to the pattern also. Such additional components of the patterns are oriented on conditions of their use, for example, in assembly operations with other parts. Necessity to take into account the diverse points of view on a pattern leads to creative tasks, which had better to solve preliminary (before making a pattern) on models, by experimenting with their decisions. The decisions that are offered in the paper are realized and checked up in the toolkit WIQA (Working In Questions and Answers) the environment of which supports conceptual modeling and conceptual programming. For designing the configured patterns, cartographical modeling of the structure and specifications of patterns, and also pseudo-code programming of their laser processing are included in WIQA functions. Inclusion in the life cycle of designing the patterns the opportunities of experimenting with their conceptual models leads to increasing the automation degree of designing and quality of its results, reducing the technological time of pattern production. The use of experimenting also promotes the prevention of mistakes and detection of mistakes, and it facilitates the porting of numerical control programs to other CNC laser cutting machine tools.
