Abstract

Polymer materials have many fields of application, such as in agriculture and agribusiness, medicine, consumer science, the automotive industry, for sports equipment etc. These materials are generally produced by injection molding, in-mold shaping and extrusion. A machining process is essential however both for small quantity production for complex and accurate shapes. Moreover, it is known that the demand for machining, especially with respect to the drilling of polymer materials has increased. In this study, the cutting temperature for drilling pure polyamide and carbon black reinforced polyamide was investigated as well as the effects of drill point angle, cutting speed, and feed rate on cutting temperature making use of Taguchi and ANOVA statistical methods. Among the selected drilling parameters, the most significant was found to be the drill point angle and the least effective the feed rate.

Kurzfassung

Polymermaterialien haben viele Einsatzfelder, wie zum Beispiel im Ackerbau, in der Agrarwirtschaft, in der Medizin, in den Verbraucherwissenschaften, in der Automobilindustrie, in der Herstellung von Sportartikeln etc. Diese Materialien werden allgemein mittels Spritzgießens, Formgebung und Extrusion hergestellt. Aber für die Produktion von kleinen Mengen ist die maschinelle Bearbeitbarkeit essentiell oder kompliziert, insbesondere für akkurate Formen. Zudem ist es bekannt, dass die Forderungen nach maschineller Bearbeitbarkeit insbesondere von Polymermaterialien zunimmt. In der diesem Beitrag zugrundeliegenden Studie wurde die Schnitttemperatur untersucht, und zwar beim Bohren von reinem Polyamid und Karbon-verstärktem Polyamid, und es wurden die Auswirkungen des Bohrwinkels, der Schnittgeschwindigkeit und der Vorschubrate auf die Schnitttemperatur untersucht, indem die statistischen Verfahren Taguchi und ANOVA angewandt wurden. Abhängig von den statistischen Studien wurde als signifikantester Bohrparameter der Bohrwinkel bestimmt und es stellte sich heraus, dass der am wenigsten effektive Parameter die Vorschubrate unter den gewählten Parametern ist.
