Research methods for processing edges of holes

The paper found that at this time is a topical solution of scientific and practical problems in ensuring quality performance parts at all edges and holes in their particular mechanical processing. The research and comparative analysis of the methods of processing the edges of the holes. On the basis of which found that existing methods of processing edges may be partially used for processing edges of holes that intersect at an angle inside the corps detail to form an ellipse edge. A promising method of treatment is elektroiskrovi edges or Electro techniques as the most flexible and environmental technology but to process the edges of the holes in the shape of an ellipse space required additional research as the shape of the electrode- tool and the modes of processing.
