Study Effects of Cutting Parameters on Surface Quality in High Speed Milling of CuZn40Pb1 Brass Alloy

In this paper, the authors developed a 4 axis high precision milling machine and using the machine to study the effect of cutting parameters on the surface roughness during high speed milling of CuZn40Pb1 brass alloy material. During machining process, the cutting forces and spindle vibration were measured to investigate the cutting forces and vibration for all the cutting conditions. Moreover, an equation of surface roughness as a function of spindle speed, feed rate, and depth of cut was established based on linear regression with least squares method. It is found that the regression equation of surface roughness shows good accuracy and agrees well with the experimental results. Moreover, the validation experiments were also conducted to evaluated the accuracy of the regression mathematical function of surface roughness. It is found that the maximum errors of the surface between validation experiments and the regression function is less than 15 which is relative small and acceptable. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
