Abstract

The work is devoted to the study of computer-aided design of wood products, as well as the development and theoretical justification of the design of complex furniture and joinery. As part of the work carried out, two methods of designing complex products were used. The first “partassembly” approach meant the assembly into a single node of previously modeled and stored parts: first placed in space, paired together and fixed. This method of modeling led to the saturation of the project with similar parts of different configurations, which required an increase in the time costs and computer power to process the connections between the parts. The second method was based on a multibody part consisting of several solids. In this case, individual parts of the product were created in one document of a multi-body part, which contributed to the reduction of complex connections between elements. For the created models of auto-components of furniture fittings, a scheme of automated placement of the main parametric element was developed, which made it possible to automatically change the dimensions depending on the dimensions of the connected parts. The use of the proposed methodology at the enterprise made it possible to design a three-dimensional model of the product, on the basis of which a full set of design documentation was obtained in accordance with the requirements of current standards, and to reduce the design time by up to 20% compared with classical design methods.
