Abstract: The present work shows the first results of the study methodology of the process parameters applied to drilling of composites reinforced with carbon fiber (CFRP) used in the aeronautical industry. The analysis uses both cutting forces and temperatures achieved in the cutting process, although it has focused on the application of IR thermography to the study of the hole. The study of the defects that can be found on the workpiece, associated with these processes (delamination), is approached by using both optical microscopy and SEM.

Abstract: Frequently, to validate FEM simulations of the cutting process it is compared the predicted results with the experimental cutting forces. In addition, other parameters are measured and it is possible to predict the chip geometry in some particular conditions. This paper presents a new development of the photogrammetry and its applications in the study of the chip geometry. In the orthogonal milling case, it is possible to obtain a 3D model of the deformed chip employing photogrammetry digitization techniques.
