The classifier of engineering processes of geokhod elements production

The present day mechanical engineering is distinguished by intense introduction of new technical solutions, adoption of science-consuming technologies, and constantly changing situation on the market. In these conditions flexibility, mobility and universality are core standards of the production process. The conditions necessitate both quality characteristics of the products to be improved regularly and manufactured articles to be substituted frequently by the new ones. Therefore, preproduction engineering is to be subjected to considerable changes. Up-to-date facilities of design automation make it reasonable to use a modular approach to the design process, when a product is made up of structural modules - uniform fabricated elements. The range of structural modules is far smaller than that of the products they can be used to manufacture. A main-line direction in classifier development is to describe a wide range of structural modules. The paper provides consideration of problems of preproduction engineering improvement, when a single-part or small-scale production of a new product (geokhod is taken as an example) is developed. The structure of products is analyzed; the latter have been arranged in groups according to structural and technological characteristics, as the consequence, the graph of complex product machining is developed with regard to particular structural characteristics. Code numbers are given to directions along the particular branches; afterwards these code numbers are used to form a code of a particular product. The process flow of the product under consideration is developed via selecting operations to treat plain surfaces (this product has them) from the flow, made for a standard product. The presented classifier makes the basis to improve efficiency of preproduction engineering, to widen the system of material and technical resources for the production process, and to further development of reference data and general improvement of production culture.
