The paper discusses tool wear characteristics in drilling of CFRP stacked on Ti-6Al-4V. A cutting simulation was applied to prediction of the cutting force, the cutting temperature and the tool wear. The flank wear progress on the end of the lips, which finish the surface in the hole, was measured in the cutting tests. The wear characteristic constants in the tool wear model were identified to minimize the prediction error in the cutting simulation. Based on the wear characteristic constants, the control factor in the flank wear progress is discussed. The flank wear progress of CFRP largely depends on the stress with abrasive effect; while, the wear in drilling of Ti alloy is sensitive to the temperature.
