Abstract
This study is to develop a parameter optimization strategy for cutting surface roughness of aluminum alloy. The machining and manufacturing process of metal parts is deeply studied, and the influence law and significance of parameters and interaction on target value are analyzed comprehensively, then the combination value of cutting parameters of aluminum alloy is optimized to ensure that the target value doesn’t exceed the specified range value. Through a series of research and analysis, the quality characteristics of processed workpiece is understood, and the difference of cutting process between aluminum alloy and other metals is distinguished. Conclusion has been drawn that the research result of cutting surface roughness of aluminum alloy provides important reference for optimizing its parameters, so it has high application value.
