Abstract
The complexity of the technology of machining by cutting complex surfaces of parts heterogeneous in terms of physical and mechanical properties and different machinability, and, in particular, of metals (aluminum) and plastics (polyurethane and polyethylene), which form an assembly component, a section of the container-type countermine system is defined in the paper. The description of technological process operations of machining of a basic detail of an item, the body, is given. Features, the presence of which creates not only difficulties in the implementation of the technological process of manufacturing a base part, but is not permissible in the operation of a defense-purpose item are revealed. The article proposes design and technological solutions for the use of a new cutting tool design, capable to eliminate errors of creep feed drilling, avoid sticking of the material of the protective shell and casing on the active cutting part, exclude damage to the contact body and thereby ensure the specified performance of the item , Field tests of a container-type countermine system with basic parts manufactured using the new tool and technology have shown high efficiency of the decisions taken.
