Soft Computing Techniques for Surface Roughness Prediction in Hard Turning: A Literature Review

open access: yesIEEE Access, 2019
Hard turning has become an attractive alternative to the more time-consuming and costly grinding technique. Unfortunately, high-quality prediction of the surface roughness generated during hard turning is difficult due to the technical complexities ...
