摘要

Nimonic C263是一种高温合金，不易切削。由于该合金含有高比例的铬、钴和钼，它们通过固溶硬化强化材料，抑制位错运动，从而产生较高的塑性变形。本研究尝试在银纳米流体混合最小量润滑(MQL)环境下，对该合金在钻孔过程中的推力、钻头刃口温度、侧面磨损和表面光洁度等加工特性进行建模、分析和研究。对不同工艺参数组合下的残余应力进行了观察和讨论。建立了基于RSM的工艺参数及多响应优化经验模型。推力、钻刃温度、表面粗糙度和刀具磨损分别受进给速度(占比60%)、主轴转速(占比88.63%)、主轴转速(占比71.42%)和进给速度(占比67.76%)及其他参数的影响。

Experimental analysis of process parameters in drilling nimonic C263 alloy under nano fluid mixed MQL environment

Nimonic C263 is a super alloy and it is difficult to cut. As this alloy possess high proportion of chromium, cobalt, and molybdenum, which fortify the material by solution hardening, which inhibits the dislocation movement, resulting in higher plastic deformation. In this research, an attempt has been made to model, analysis and investigate the machining characteristics such as thrust force, temperature at drill cutting edge, flank wear and surface finish during drilling of this alloy using silver nano fluid mixed Minimum Quantity Lubrication (MQL) environment. Residual stress at various combinations of process parameters was also observed and discussed. RSM based empirical models of the process parameters and optimization of multi response was developed. Thrust force, Temperature at drill cutting edge, surface roughness and tool wear affected by feed rate (percentage of contribution-60%), spindle speed (percentage of contribution-88.63%), spindle speed (percentage of contribution-71.42%) and feed rate (percentage of contribution-67.76%) respectively followed by other parameters.
