数控雕铣加工铝合金材料进给速度的优化与实验验证

Feed Velocity's Optimization and Experimental Validation of Aluminum Alloys Machined by CNC Engraving Machines

针对数控雕铣机床加工铝合金件的特点,运用多目标优化理论,建立了加工成本与加工效率的数学模型.经过计算,得到了一系列的进给速度的优化解.经过实验加工和验证,最终得到了在该条件下较为理想的进给速度取值范围（Vf∈2400~2560 mm/min）.研究表明,以该进给速度范围进行加工铝合金材料时,能够以相对较低的加工成本和较高的效率得到良好的表面质量.

Based on the features of aluminum alloy milled by CNC engraving machines,the mathematical model of the processing cost and processing efficiency has been established by Multi-objective Optimization Theory,and then a series of optimized solutions are calculated with it.By experimental machining and verification,the relatively ideal value range of feed velocity is obtained,which is between 2 400～2 560 mm/min.It is shown that,when machined with the proposed feed velocity range,aluminum alloy can achieve a better surface quality with relatively low processing cost and high efficiency.
