Annotation.

The task for the course project is based on factory practice held at the Lianozovsky Electromechanical Plant, the project considers the process of assembling the Coaxial Transition and manufacturing the Hull part. The project proposes processing technology, and the assembly process of the node developed for training purposes.

The note consists of two sections. Section A is devoted to the development of the process of assembly of the "Coaxial transition" node. The assembly assembly is described. Technical requirements and tasks arising during assembly are analyzed, soldering problems are solved. The process of assembly with filling of the roadmap is being developed.

Section B is devoted to designing the manufacturing process of the housing part. A brief description of the part assignment in the subassembly is given. Part Design Processability Analysis. You select the production method for the workpiece. Hazardous places shall be checked for stresses occurring in them during fabrication. The CNC lathe program is written. Routing and operating technologies for the manufacture of a part with the filling of a roadmap are being developed. Equipment, cutting and measuring tools are selected.
