The paper is focused on the experiment where the effects of the cutting environment and feed of drilling on the bores roughness and cylindricity were evaluated. Dry drilling of aluminium alloys (without using cutting fluids) is an environmentally friendly machining process but also an extremely difficult task, which is due to the tendency of aluminium to adhere to the drills made of conventional materials such as high-speed steel; and therefore three cutting environments (namely two different emulsions and compressed air) were used in the experiment. The article demonstrates multicriterial optimization of input factors (cutting environment, feed) for two defined target functions: roughness and cylindricity). The measured values were subjected to mathematico–statistical Analysis of Variance (ANOVA). ANOVA was used for examining the effects of machining parameters and their contribution to the surface roughness and bores cylindricity. The optimal cutting parameters were evaluated for “Smaller-the-Better” quality characteristics of both output responses, as can be seen in our article published previously. Based on the ANOVA, we determined that cutting environment exhibited higher percentage of contribution on bores quality than feed of machining. The results show 77.37 % impact of cutting environment and 8.13 % impact of feed on quality of machined bores.

“…A certain number of important properties of the tool material such as hardness, strength, temperability and thermal conductivity are required to ensure a long lifetime of cutting tools [11]. There are several publications which investigated the influence of tool geometry on the tool wear [12], [13]. Issue of edge preparation affecting the macro geometrical properties of cutting tools, was not thoroughly investigated, that is why the following research has been carried out.…”

The paper deals with the comparison of milling tools geometry after drag finishing with various times. The aim was to determine the influence of drag finishing on macro geometry of the solid cemented carbide mills. The article describes tool geometry deviance after grinding process and the influence of drag finishing on rake angle, flank angle and diameter of the tools. The cemented carbide material with chemical composition WC + Co (10%) was used for this research. The tools were manufactured on the Reinecker WZS 60 grinding machine from cemented carbide rod. The tool geometry of cutting tools was measured on ZOLLER genius 3 optical measuring machine. The drag finishing process was carried out on OTEC DF-3 Tools drag finishing machine with OTEC SIX 70/16 grinding granulate. It was found the accuracy of cutting tools manufactured on grinding machine, and the deviation of rake and flank angles was 2° and tool diameter was 0.08 mm.

During the drilling process of the aluminium alloy, certain specifications are different from milling and turning. The major differences: 1) a variable cutting speed along the main cutting edge, 2) more difficult chip evacuation, 3) poor access of liquids into the cutting area. One of the problems is to select a suitable cutting environment for drilling the aluminium alloy to ensure the required quality of the bore (mainly roughness and cylindricality). Dry drilling of aluminium alloys (without using cutting fluids) is an environmentally friendly machining process but also an extremely difficult task due to the tendency of aluminium to adhere to the drills made from conventional materials such as high-speed steel, therefore three cutting environments (namely two different emulsions and compressed air) were used this experiment. The paper is focused on the experiment where the effects of the cutting environment and feed of machining on the bores roughness and cylindricity are evaluated. The article demonstrates multicriterial optimization of input factors (cutting environment, feed) for two defined target functions roughness and cylindricity). The measured values were subjected to mathematical statistical analysis Desirability Function Analysis (DFA). Based on the experiment and studies on this issue combinations of input factors have been identified that have achieved minimum target function values. The results show that the most appropriate combination of the following input factors has been demonstrated: compressed air and feed setting at the lowest level, ie 0.2 mm.
