Abstract
The paper presents the methodology of designing the production process of a new product from the point of view of the criterion of the assembly operations technology (Design for Assembly - DFA) in the automotive industry. The article describes methods and techniques used during the implementation of a new product into production. The impact of the methods on improving the assembly technology of a complex product is described. Suggestions for improving for unit and small series production are presented.
Highlights
To evaluate the technology of the assembly and defined guidelines for shaping the design process due to PDM (Product Data Management - PDM), different methods may be used
Widely recognised methods known as DFA were proposed and described for the first time by G
By introducing the DFA methods into the design process, the new product design team can propose improved design solutions, which are characterized by better indicators, simpler construction and components, which directly affect the simplification of assembly operations
Summary
To evaluate the technology of the assembly and defined guidelines for shaping the design process due to PDM (Product Data Management - PDM), different methods may be used. The DFA methods are constantly being refined due to technical progress They allow a more efficient evaluation of the possibility of reducing the number of product components and estimating the costs of machining processes and assembly of the analysed product. By introducing the DFA methods into the design process, the new product design team can propose improved design solutions, which are characterized by better indicators, simpler construction and components, which directly affect the simplification of assembly operations. The most popular methods of the DFA practice are Lucas DFA, Boothroyd and Dewhurst (B & D), Hitachi AEM. Development of machining technology (thanks to the automation and extension of the possibility of making objects of complex construction), in connection with a significant share of manual work in the assembly processes of finished products, has led to a change in the approach to the production of new products. The assessment is based on marketing and conceptual preparation; documentation - construction, production and organization; implementation of the production process; distribution; conditions for the operation and decommissioning of the product
