The possibilities of using of group technologies for manufacturing the parts of universal-assembled devices

The manufacture of parts and assembly units of the aerospace industry is characterized by a small product range, but a significant changeability of their shape and size. In these circumstances, the use of the elements of universal as- sembly devices (UAD) allows to reduce the number of special devices significantly. Based on the results of a complex research on the analysis of design and manufacturing technology of elements of UAD, and on the known principles of construction of group technologies the algorithm for the formation of technological groups of UAD details of the ”prism support” type was developed. The 3D-model of the complex details, the classification of surfaces proposed for it and the database on all 16 details of the group are the basis for the development of an algorithm for a route group technological process (GTP). In the new GTP and control program it is proposed to combine in one operation practi- cally all draft types of processing: milling, drilling, thread cutting on the multi-task machine with the palletization of complex details on a technological plate. The effectiveness of the constructive-technological decisions is confirmed by the reduction in the number of operations and equipment (from 7 to 4 machines) thus reducing the labor content and cost. The use of the developed techniques of development the GTP allows significant expansion of the possibilities for automation of technological preparation of production, simplifies the development of control programs, reduces the labor content of the preparation of technological documents and its translation into digital form.
