Abstract
Each industrial enterprise, in order to increase the competitiveness of its products, must ensure such quality indicators as dimensional stability and maintainability during the entire warranty period. In practice, these indicators are ensured by observing the design rules. This problem is especially relevant in the design of joinery and construction and furniture products operated in variable climatic conditions. The purpose of the study was to establish the optimal technological chains for the production of re-adhesive structural elements; find the optimal sizes of lamellas, plots and assembly units for gluing; substantiate the expediency of veneering the glued elements with sawn veneer; design of products as a whole without the use of spikes and glue. All studies were carried out in real production conditions: at LLC Firm "Caucasian Forest", Republic of Adygea, Maikop district, settlement Tulsky and LLC HC "Mebel Chernozemya ", Voronezh. It is clear from the studies carried out that the technology of re-glued blanks allows several times to reduce warpage and increase the dimensional stability of structural elements; veneering operation allows rational use of low-grade wood in production
