As an example, we considered the package design of a product, consisting of parts (aluminum, polyurethane) of a complex structural form, intended for ejection on the ground with significant dynamic loads. The article shows an analysis of the difficulties associated with the manufacturing of a deep hole in a package of different structural materials. We formulated general requirements for both the cutting tool and the assembly operation, which completes the process of manufacturing the product. In addition, we justified the brand of the cutting tool material, which provides the necessary operability and the design of a special dual-use tool – capable of processing a deep hole and creating a fit in the package of the assembly unit.
