“…This tendency was more pronounced in drill I, taking up a surface of 3 mm in the direction of the helix and 1 mm wide. Although the craters do not affect the cutting edge geometry, (and apparently, do not affect cutting process), they weaken the tool [20].…”

This work is focused on the combined study of the evolution of tool wear, quality of machined holes and surface integrity of work-piece, in the dry drilling of alloy Ti-6Al-4V. Tool wear was studied with optical microscope and SEM-EDS techniques. The quality of machined holes was estimated in terms of geometrical accuracy and burr formation. Surface integrity involves the study of surface roughness, metallurgical alterations and microhardness tests. The end of tool life was reached because of catastrophic failure of the drill, but no significant progressive wear in cutting zone was observed previously. High hole quality was observed even near tool catastrophic failure, evaluated from the point of view of dimensions, surface roughness and burr height. However, microhardness measurements and SEM-EDS analysis of work-piece showed important microstructural changes related with a loss of mechanical properties. Depending on the application of the machined component, the state of the work-piece could be more restrictive than the tool wear, and the end of tool life should be established from the point of view of controlled damage in a work-piece.

“…The thrust forces obtained in TiN coated drills were better than those obtained in TiAlN coated drills. It is thought that thrust forces were found low as a result of low friction coefficients of TiN coatings [2, 4,5]. The lowest value measured with a TiAlN/TiN coated drill is 554 N at feed rate of 0.063 mm/rev and cutting speed of 60 m/min.…”

In this study, the effects of cutting speed, feed rate and different types of coating materials on thrust force and hole diameter were investigated in drilling of AISI D2 cold work tool steel. In addition, the thrust forces and hole diameters were predicted by artificial neural networks (ANN) using experimental data. Uncoated, TiN, TiAlN monolayer and TiAlN/TiN multi-layer coated cemented carbide drills with diameter of 5 mm were used in drilling experiments. The holes were drilled at different combinations of four cutting speeds (50, 55, 60, 65 m/min), two feed rates (0.063 and 0.08 mm/rev), and fixed depth of cut (7 mm). Experimental results showed that the lowest thrust forces and hole diameters were obtained with TiAlN/TiN multi-layer coated drills. After ANN training, it was found that the R 2 values are very close to 1 for both training and test sets. RMSE values are smaller than 0.03, and mean error values are smaller than 5% for the test set. This case shows that ANN is a powerful method for prediction of thrust forces and hole diameters.

“…Many researchers have carried out experimental investigations to study the effects of process factors on burr formation mechanisms during drilling of several workpiece materials (Stein and Dornfeld, 1997;Dornfeld et al, 1999;Lin, 2002;Ko et al, 2003). In order to analyze the burr formation mechanisms in drilling, finite element models were employed (Guo and Dornfeld, 2000;Min et al, 2001a).…”
