Machining of curve shapes is a necessity in micro-milling process. However, surface roughness in micro-milling curved surfaces is more complex, and few studies on the influence factors and prediction of the micro-milled curve surface roughness in micro-milling nickel-based superalloy have been done. The purpose of this paper is to study the effects of spindle speed, the radius of ball-end mill, axial cutting depth, and feed per tooth on the curved surface roughness in micro-milling Inconel 718 process based on single factor and orthogonal experiments. Utilizing the least square method, we build a surface roughness prediction model of micro-milled Inconel 718. Finally, experiments are conducted to verify the accuracy of the developed prediction model. The results indicate that the maximum relative error is 10.68%, and the mean relative error is 8.04%, which prove that the prediction model is correct. The work can provide a reference for selection of cutting parameters in micro-milling Inconel 718. 发表时间:2018-01-01
