Influência do sistema de fixação e da vibração no desgaste da ferramenta durante o fresamento

Abstract

This study investigates the influence of the tool holding system on tool wear in milling operations, comparing collet and hydraulic adapters. While the collet holder is more economical and widely used, it has limitations regarding imbalance, runout, and vibrations, which compromise precision and tool life. In contrast, the hydraulic holder offers greater stability and accuracy, despite its higher cost. The study addresses various types of wear, such as flank and notch wear, as well as severe damages like cracks and chipping, which directly affect production performance. It analyzes wear mechanisms including adhesion, abrasion, diffusion, and oxidation, which act specifically on the materials of both the tool and the workpiece. Tool life is assessed through flank wear (VB), a key durability indicator. Furthermore, the research examines how the holding systems influence imbalance, runout, and vibrations, resulting in irregular wear patterns. It concludes that the proper choice of tool holding system, combined with strict control of machining parameters, is essential to optimize tool life and process efficiency.
