The present work is based on a series of short tests (no longer than ten seconds) of dry turning. The tests have been made on cylindrical bars of UNS A92024‐T3 aluminium for different values of the cutting conditions (cutting speed and feed) and types of tools. Namely, two types of tools with identical geometry and different coatings (coated with TiN and uncoated) have been tried. The investigation is focused on analysing the relationship between the surface roughness of the bars obtained in the tests and the cutting parameters for both types of tools. A comparison between the results obtained for both tool coatings shows that, in general terms, the surface quality reached using coated tools is better than the obtained with uncoated ones. Considering the cutting parameters, the experimental results show that, with independence of the tool used, the lower the feed, the better the surface finish. Finally, taking into account the cutting speed, is possible conclude that the increase of the cutting speed when using low feed rates suppose a reduction of the surface roughness.
