About the methodology for developing the route of the technological process of manufacturing forest engineering products

Recommendations on the design of technological processes in machine-building industries are often fragmented and require generalization by product type (part, assembly unit, product as a whole) for the most typical conditions of industrial engineering. The use of modern automation systems for engineering calculations (CAD/CAE/CAM) also necessitates the formation of general system requirements, which determined the purpose and objectives of the presented work. The article discusses the methodological issues of forming the route of technological processes for manufacturing parts and assembling products in forestry engineering. The process of technology creation is divided into parts, the tasks of each stage and the most rational ways to solve them are formulated. The principles of forming the structure of the process, the sequence of transitions and technological operations are presented. Recommendations have been formed on the differentiation of the created object both by processing surfaces and the number of assembly units, taking into account the peculiarities of repair and small-scale production. The material is illustrated with examples of the design of processes formed in compliance with these recommendations (manufacturing technology of the saw blade of the gripping and shearing device of the felling machine). The efficiency of creating assembly processes can be significantly increased by the preliminary development of assembly schemes. The issue of improving the quality of work of a process engineer using modern CAD/CAM/CAE systems that ensure effective work with databases and structural elements of the technology tree is considered. The variants of the formation of assembly diagrams illustrated using the program «SOLIDWORKS», the Composer application are presented.
