Synthesis the Structure of the Technological Cutting Process

One of the directions of technological processes (TP) improvement of processing by cutting operations is the development of applications for automating the synthesis of TP machining, and the synthesis is carried out in two stages: the first is the structural optimization of TP in the form of TP operations sequence; the second is the parametric optimization of TP, where the search for optimal modes of operations is carried out. A decision of support system for the structural optimization of the TP cutting metal processing that is used for the high-precision products of aviation equipment, which makes a rational choice of the set of TP components in the form of a set of part surfaces, work pieces, equipment, fixtures, tool, lubricating and cooling technological environments are used in the enterprise and possible operations is proposed in the paper. The solution is formed on the basis of the developed heuristic rules for the selection of TP components that take into account technical and technological data on TP components, the requirements of standards, regulatory and industry metalworking documents, accumulated knowledge in the field of the theory of mechanical machining and the experience of process experts. With this approach, the problem has a finite set of solutions, formed as a set of alternative TP. The final decision on the TP structure is formed after determining the optimal modes of operation - cutting speed and feed, according to the specified objective functions. To solve the problem which is formalized in the form of a decision tree, a method of sequential hierarchical synthesis and methods of artificial intelligence, namely, production rules implemented using the logic programming language, are applied. The testing made on the example of TP processing a specific product.
