Appraisal of the Drilling Speed Influence on the Evaluated Residual Stress Values

There are several methods for determining residual stresses inside the constructions. Recently the most common methods are those which do not destroy the inspected components which are thus still fully usable. Hole-drilling method represents this kind of methods. It is standardized by internationally respected standard ASTM E837. It describes the recommendations for the residual stress measuring process for the hole-drilling method. One of the described factors is the influence of the drilling speed. In this paper the measuring experiment for the evaluation of the drilling speed influence on the acquired residual stress values purpose is described and accomplished.
