In the present investigation, the influence of machining parameters during turning on the surface characteristics and material removal rate of epoxy/BN nanocomposites. The influence of machining parameters, typically, the feed rate, cutting speed, and depth-of-cut on the surface characteristics of epoxy/BN nanocomposite workpieces, typically, the surface roughness (Ra) and roundness error (Er) were evaluated. Moreover, the influence of the aforementioned machining parameters on the material removal rate of epoxy/BN nanocomposites was investigated. Empirical regression models were developed to estimate influences of the aforementioned independent variables on the MRR, Ra and Er.
