Methods and Ways for Ensuring Increased Hole Quality in Composite Material Drilling

Composite materials are intensively used in manufacture of new products due to many advantages, when compared to metals. However their inhomogeneous and highly abrasive reinforcements create machining difficulties. The most frequently used machining in drilling, because it is necessary to fabricate a large number of holes in order to connect composite material parts with other parts. During drilling intensive tool wear, dust generation and specific hole damage (hole fabrication deviations) occur. Drilling damage and errors are to be reduced to minimum or completely removed, thus achieving high hole fabrication quality. In this paper, elements for forming useful value matrix, hole fabrication method and means decision making with elements for hole fabrication optimization by drilling in composite materials, are given.
