镍基超合金通常用于航空航天工业中的不同应用，例如，整体叶盘或涡轮机叶片。由于其高强度和耐腐蚀性，Inconel 718等材料导致机械加工性差，从而导致大量的刀具磨损。本文分析了不同工艺参数值对刀具磨损的影响。对于基本的调查，刀具磨损的演变进行了检查，两种不同的路径策略，有和没有冷却剂。为了确定合适的工艺参数值，后刀面磨损区宽度和工艺力进行了分析的基础上筛选设计的实验。
Nickel-based superalloys are often used in aerospace industry for different applications, e.g., blisks or turbine blades. Due to its high strength and corrosion resistance, materials like Inconel 718 lead to a poor machinability and, thus, to a high amount of tool wear. In this paper, the influence of different process parameter values on the tool wear is analyzed. For the fundamental investigations, the tool wear evolution was examined for two different path strategies with and without coolant. To identify suitable process parameter values, the width of flank wear land and process forces were analyzed based on a screening design of experiments.
