摘要
为探究单晶铝微尺度铣削的表面质量,采用直径为0.4mm的微铣刀对单晶铝进行三因素五水平的微尺度铣削正交实验。首先,通过极差分析的方法得到:主轴转速对其表面质量的影响最大,进给速度的影响次之,铣削深度的影响最小;得到的最优工艺参数组合为:主轴转速为36000r/min,铣削深度为10μm,进给速度为80μm/s,此时单晶铝的表面质量最好。然后,分别得到主轴转速、铣削深度和进给速度对表面质量的影响规律,并对其原因进行了深入分析,为单晶铝材料的微尺度铣削加工提供理论依据。
In order to explore the surface quality of singlecrystal aluminum in micro-milling, a three-factor and five-level orthogonal experiment of singlecrystal aluminum in micro-milling was conducted by a micro-milling toolwith a diameter of 0.4mm. Firstly, conclusions can be drawn as the following with the method of range analysis： The spindle speed has the greatest effect onsurface quality and the feed rate follows. However, the milling depth has the least effect onsurface quality. The optimized parameters combination is as the following： Spindle speed is 36000r/mitt Milling depth is 10μm. Feedrate is 80μm/s. The surface quality of singlecrystal aluminum is the greatest with the parameters above. Then the influence of spindle speed andmilling depth and feed rate on surface quality was obtained respectively. Deeply analysis of its causes were also given,providing a theoretical basis for the processing of singlecrystal aluminum material in micro-milling.
