The effect of cutting parameters, such as depth of cut, feed rate, spindle speed, cutting fluid flow rate and the number of layers deposited on the surface roughness and flank wear of a cathodic arc evaporation coated TiAlN/WC-C tungsten carbide cutting tool insert was investigated during CNC turning of AISI 1015 mild steel. The analysis of variance was applied to determine the critical effect of the cutting parameters. Taguchi orthogonal test design was used to optimize the process parameters. The depth of cut and deposition of layers altered the surface roughness (49 and 32 %, respectively) of the inserts. However, cutting speed, feed rate and the flow rate of the cutting fluid contributed only minimally to the surface roughness. In contrast, the number of layers deposited (48.66 %) and cutting speed (30.93 %) were the dominant factors affecting tool wear. The optimum cutting conditions for achieving the desired surface roughness consist of a medium level of cutting speed, a low depth of cut level, a low feed rate, high flow rate of cutting fluid and multilayer deposition. Minimal tool wear was achieved for the process parameters such as low cutting speed, low depth of cut, medium feed rate, medium flow rate of cutting fluid, and a multilayer deposited tool.


Die Auswirkungen der Schneidparameter, wie der Schnitttiefe, der Vorschubrate, der Spindelgeschwindigkeit, der Durchflussrate des Schneidmittels und der Anzahl der Lagen auf die Oberflächenrauheit und den Flankenverschleiß von Wolframkarbid-Schneideinsätzen, die mittels Lichtbogenverdampfens mit TiAlN/WC-C beschichtet wurden, wurden während des CNC-Drehens eines Kohlenstoffstahles des Typs AISI 1015 untersucht. Um kritische Auswirkungen der Schneidparameter zu bestimmen, wurde eine Varianzanalyse angewandt. Um die Prozessparameter zu optimieren kam das orthogonale Taguchi-Verfahren zum Einsatz. Die Schnitttiefe und die Zahl der Lagen veränderten die Oberflächenrauheit (um entsprechend 49 und 32 %). Allerdings wiesen die Schnittgeschwindigkeit, die Vorschubrate und die Durchflussrate des Schneidmittels nur eine minimale Auswirkung auf die Oberflächenrauheit auf. Im Gegensatz waren die Zahl der Lagen (48,66 %) und die Schnittgeschwindigkeit (30,93 %) die dominanten Faktoren, die den Werkzeugverschleiß beeinflussen. Die optimalen Schnittbedingungen, um die erforderliche Oberflächenrauheit zu erbringen, liegen bei einem mittleren Niveau der Schnittgeschwindigkeit, einem niedrigen Niveau der Schnitttiefe, einem niedrigen Niveau der Vorschubrate, einer hohen Durchflussrate des Schneidmittels und einer Viellagentechnik der Werkzeugbeschichtung. Ein minimaler Werkzeugverschleiß wurde für die entsprechenden Prozessparameter erreicht, wie eine niedrige Schnittgeschwindigkeit, eine geringe Schnitttiefe, eine mittlere Vorschubrate, eine mittlere Durchflussrate des Schneidmittels und einer Viellagentechnik der Werkzeugbeschichtung.
