Análise de viabilidade técnica no uso de revestimento em brocas de canal reto para furação de ferro fundido vermicular

Abstract

Coatings for cutting tools are of great importance in the evolution of production processes, using them in drills makes drilling optimized. Drilling is usually the last process to be performed, therefore, it has great weight in machining. The objective of this work is to analyze the feasibility of implementing the coating in straight flute drills in the drilling of vermicular cast iron, for which the flank wear of the tool will be analyzed. By quantifying the useful life of the tool, positive increases in production can be generated, making the study viable. The methodology was based on bibliographic and field research, focusing on the measurement of flank wear using the stereoscope. According to the intervals and numbers of machining cycles, it was possible to generate the tool life curve, noting that it is advantageous for straight flute drills to use TiXCo³ in the drilling of vermicular cast iron.
