MODELING OF GRAPHIC IMAGES ON PRODUCTS OF COMPLEX SHAPE The aim of the study is to develop and substantiate methods for 3D modeling of graphic images on complexshaped products using CAD systems for subsequent mold design. The article examines methods of 3D modeling of graphic images on complex-shaped products in modern CAD environments for their further application in mold design. The features of forming relief and recessed elements on curved surfaces are analyzed, the limitations of standard modeling tools are identified, and an algorithm for constructing parametric models is proposed, taking into account technological requirements for the manufacture of forming tooling. The obtained results make it possible to improve the accuracy of geometric reproduction of graphic elements, reduce the time required for mold design, and ensure compliance of models with production requirements. The capabilities of parametric modeling tools for creating relief and engraved elements are investigated. An algorithm for constructing a 3D model of a product with an integrated graphic image is developed. The features of forming geometry suitable for further mold design are determined. The methods of 3D modeling of graphic images on surfaces of complex spatial shape are improved, taking into account the requirements for designing molds for soap production, and relationships between the parameters of the graphic relief and the design features of forming tooling are established. The influence of surface types on the quality and clarity of graphic element reproduction during the forming process is also analyzed. The feasibility of using adaptive smoothing parameters and controlling draft angles is substantiated, which allows for improved separation of the product from the mold
