Cutting Tool Materials

The design concept of functionally graded materials was first introduced into the development of self-lubricating ceramic cutting tool materials. An Al2O3/TiC/CaF2graded self-lubricating ceramic cutting tool material was designed and fabricated. Mechanical properties were evaluated by comparing with those of Al2O3/TiC/CaF2homogeneous self-lubricating ceramic cutting tool material. The results showed that the Al2O3/TiC/CaF2graded self-lubricating ceramic cutting tool material had superior performance to the counterpart. Graded self-lubricating ceramic cutting tool materials are bound to have promising prospect in the field of high speed dry machining.

Different Levels

A single point cutting tool is modeled out of two different materials having desired thermoelectric properties. The tool material used is B4C doped with different compositions of Titanium Carbide. In the present work, three different compositions of B4C doped on both sides of cutting tool made by tungsten carbide. The range of composition of boron carbide (B4C) was selected randomly with 0-12.5%, 0-25.4% and 12.5 – 25.4% of B4C on first half and second half of the cutting tool respectively. The simulation process is done in ANSYS 2020 R2 software, thermal-electric module (TEM) is used. From these studies it is evident that considerable cooling effect is achieved and found to be the lowest temperature of 14.960C is observed for 0-25.4% B4C, 18.790C is observed for 0- 12.5%B4C and 26.730C for 12.5-25.4% B4C at the junction of the materials which is nearer to the cutting tip respectively. Finally it is concluded that  one side of cutting tool without any doping  and other side with 25.4% B4C doped showed good results which observed by conducting number of simulations at different levels of iterations for B4C doped titanium carbide cutting tool used in turning operation.

The Impact

Als mögliche Substitution des konventionellen Hartmetalls Wolframcarbid (WC), wird Niobcarbid (NbC) für den Einsatz in Zerspanwerkzeugen getestet. Es werden verschiedene NbC-Spezifikationen verwendet, die sich in der chemischen Zusammensetzung und den mechanischen Eigenschaften unterscheiden. Trockene Außenrunddrehversuche an Kohlenstoffstahl C45E, Zahnradstahl 42CrMo4+QT und der Aluminiumlegierung AlSi9Cu4Mg werden durchgeführt, um verschiedene NbC-Schneidstoffe mit handelsüblichen WC-Werkzeugen zu vergleichen. Um die Auswirkung einer höheren thermomechanischen Belastung während der Bearbeitung aufzuzeigen, wird die Schnittgeschwindigkeit variiert. Die Zerspanungsleistung aller untersuchten Versuchswerkstoffe wird hinsichtlich Spanvolumen Vw, Kolkverschleiß KT sowie der erreichbaren Oberflächenrauheit Ra und Rz des Werkstücks beurteilt. Im Rahmen der Untersuchungen wird bei erhöhten Schnittgeschwindigkeiten vc eine verbesserte Werkzeugleistung der verschiedenen NbC-Schneidwerkzeuge im Vergleich zum WC-Referenzmaterial aufgezeigt. Der Vergleich der Oberflächenqualität der Werkstoffe nach der Zerspanung zeigt, dass NbC, trotz sporadisch höherer Verschleißraten, vergleichbare Oberflächenqualitäten liefert. Die prototypischen NbC-Schneidstoffe erreichen bei der Zerspanung von C45E ein höheres Spanvolumen Vw als das WC-Referenzsubstrat. Für die Bearbeitung von 42CrMo4+QT und AlSi9Cu4Mg sind Weiterentwicklungen notwendig, um höhere Standzeiten zu erzielen.   In order to investigate a possible substitution of the conventional substrate material tungsten carbide (WC), niobium carbide (NbC) is tested for the use as a cutting tool in turning processes. Different straight NbC materials are applied, differing in chemical composition and mechanical properties. Dry external cylindrical turning tests on carbon steel C45E, gear steel 42CrMo4+QT and aluminium alloy AlSi9Cu4Mg are carried out comparing various NbC based cutting materials with commercially available WC-based tools. Cutting speed is varied to show the impact of higher thermomechanical load during machining. The cutting performance of all investigated cutting tool materials is assessed regarding material removal VW, crater wear KT as well as surface roughness Ra und Rz of the workpiece. Improved tool performance of different NbC cutting tool grades compared to commonly applied WC tool material at increased cutting speeds vc is demonstrated within the investigation. The comparison of the surface quality of the workpiece materials after the cutting process shows that NbC produces comparable surface qualities despite occasional higher wear rates. Prototypical NbC cutting materials achieve a higher material removal VW during the machining of C45E than the WC reference substrate. For the machining of 42CrMo4+QT and AlSi9Cu4Mg, further developments are necessary to achieve longer tool life.
