摘要 为研究微小刃径刀具切削难加工材料后刀具的磨损,针对单晶镍基高温合金材料的难加工特性,设计了单因素实验方案,采用直径为0.6 mm的硬质合金微小刃径刀具对单晶镍基高温合金DD98进行微铣削加工;通过磨损后的刀具直径和铣削槽底宽度尺寸的变化来定义微铣削刀具(微小刃径刀具)切削加工的磨损标准,建立了微铣削刀具磨损标准的数学模型;基于单因素实验方案,探讨了不同切削参数条件下,微铣削长度对刀具磨损量的影响。相关研究和实验数据对于探索难加工材料的切削机理具有理论指导意义。 To study the wear of difficult-to-machining materials for micro-edge radius tool,the single-factor experimental scheme was designed considering the hard-machining properties of single crystal nickel-based superalloy material,the single crystal nickel-based superalloy DD98 was micro-milled with 0.6 mm diameter carbide tool.The wear standard of micro-milling tool(micro-edge radius tool)was defined by the change of tool diameter after wear and the width of milling groove bottom.The mathematical model of wear standard of micro-milling tool was established;based on the single-factor experimental scheme,the influence of micro-milling length on tool wear under different cutting parameters was discussed.The relevant mechanism and experimental data have theoretical guiding significance for exploring the cutting mechanism of difficult-to-machining materials.
