THE DEVELOPMENT OF ENGINEERING SUPPORT FOR LOOSE ABRASIVE WORKING METHODS

The trends of working methods development based on the analysis of certain working methods using loose abrasive are giv-en. Along with wide technological capabilities and relatively low cost, the existing irregularities of methods are noted. The elimination of them will ensure prospective viability for the development of machining operations with the use of loose abra-sive. An approach was suggested. It consists in forming the structure of databases of working methods according to struc-tural and technological features and generating groups of methods differing in homogeneous design procedures for their development using a mathematical tools technique of cluster analysis. The article describes and provides diagrams of the developed methods of external and internal surfacing of rotation body type using a compacted layer of abrasive medium. They make it possible to get not varying qualitative characteristics, finishing through forming an area of abrasive material in the chamber with equal compaction in the places of interaction of the treated surface and abrasive grains, and to provide conditions for equalization of contact pressures on the working surface. Based on the performed research and testing of the presented methods, scientific and technical tasks have been identified, the solution of which will make it possible to imple-ment the technological support of their effective application. For the purpose of reducing the complexity of the created mod-els and the volume of experimental research, a strategy for conducting research based on the unification of individual pro-ject procedures for technological preparation of production is proposed. The obtained results allowed making theoretical substantiation of a systematic approach to the formation of an environment for automated planning of operations using loose abrasive, which consists in the creation of formalized homogeneous design procedures for grouped working methods.
