The paper presents a method of drilling in ceramics materials, applied for the determination of macroscopic residual stresses. To this end, high frequency vibrations of the ultrasound waves exercised on a drilling device are utilized. The shape and dimensions of the resulting hole depend on the shape and dimensions of the drilling device. The advantages of this method are: no additional stresses result from the application of this drilling procedure, the resulting hole has a satisfactory precision and the experiment may be repeated, macrostresses' variation in the studied material's depth may be determined.
