Abstract
The main aim of machining is to provide the dimensional preciseness together with surface and geometric quality of the workpiece to be manufactured within the desired limits. Today, it is quite hard to drill widely utilized Ti-6Al-4 V alloys owing to their superior features. Therefore, in this study, the effects of temperature, chip formation, thrust forces, surface roughness, burr heights, hole diameter deviations and tool wears on the drilling of Ti-6Al-4 V were investigated under dry cutting conditions with different cutting speeds and feed rates by using tungsten carbide (WC) and high speed steel (HSS) drills. Moreover, the mathematical modeling of thrust force, surface roughness, burr height and tool wear were formed using Matlab. It was found that the feed rate, cutting speed and type of drill have a major effect on the thrust forces, surface roughness, burr heights, hole diameter deviations and tool wears. Optimum results in the Ti-6Al-4 V alloy drilling process were obtained using the WC drill.
Kurzfassung
Das Hauptziel der maschinellen Bearbeitung besteht darin, die dimensionale Präzision sicherzustellen, zusammen mit einer guten Oberflächenqualität und geometrischen Qualität des Werkstückes, das jeweils unter den gegebenen Randbedingungen hergestellt werden muss. Heute ist es immer noch schwer, die vielfach genutzten Ti-6Al-4V-Legierungen aufgrund ihrer überragenden Eigenschaften zu drehen. Deshalb wurden in der diesem Beitrag zugrunde liegenden Studie die Temperatur, die Spanbildung, die Wirkkräfte, die Oberflächenrauheit, die Grathöhen, die Lochdurchmesserabweichungen und die Werkzeugverschleiße beim Bohren von Ti-6Al-4 V unter Trockenschneidbedingungen bei verschiedenen Schnittgeschwindigkeiten und Vorschubraten von Bohrern aus Woframcarbid (WC) und Hochgeschwindigkeitsschnellarbeitsstahl (HSS) untersucht. Darüber hinaus wurde eine mathematische Modellierung der Wirkkraft, der Oberflächenrauheit, der Grathöhen, der Lochdurchmesserabweichung und der Werkzeugverschleiße mittels Matlab durchgeführt. Es stellte sich heraus, dass die Vorschubrate, die Schnittgeschwindigkeit und der Bohrerwerkstoff erhebliche Auswirkungen auf die Wirkkraft, Oberflächenrauheit, Grathöhen, Lochdurchmesserabweichung und der Werkzeugverschleiße haben. Die besten Ergebnisse beim Bohren der Ti-6Al-4V-Legierung wurden mit dem WC-Bohrer erreicht.
