Friction plays an important role in stick-slip motion which is an undesirable phenomenon in engineering applications. We focus on studying frictional behaviour of contacting solids during sliding and cutting and the associated dynamic effects which are critical for the stick-slip motion and friction reduction. The effect of vibrations on friction reduction and the efficiency of cutting with the influence of rock fragments in front of and under the cutter are determined. The thesis highlights the profound effects of the elasticity of the material and the non-sphericity of the grains/cuttings on stick-slip behaviour and friction force fluctuations.
