Análise de temperatura em ferramentas polidas no processo de fresamento

Abstract

Among all machining processes, milling stands out for it is high productivity and versatility. The requirement for more efficient, reliable, affordable and quality processes, inflicted those milling enhancements technologies were developed, to achieve that, countless machining variables were studied, such as different geometries and materials of cutting tools, cutting speeds and heed with the cutting environment. The machining parameter to be validated in this study is the cutting edge preparation. The tool will be polished so it is influence on improvements in the machining are validated. Milling process can achieve high temperatures along the cutting, which can cause micro-structural distortions and modifications that can impact the machining process. Therefore, to analyze the temperatures, this study achieved to embed thermocouples on the workpiece, so the temperature data presented is for workpieces measurements. This paper managed to develop an efficient and simple reproduction method to drill the tools, consequently perform a perforation on a tool without edge preparation. Finally, after confronting the results with other studies and acquisition of temperature data, the polishing effectiveness of top milling tools edge preparation using the HSC 1/300 granulate has been positively substantiated.
