Comparison of Hard Machining Procedures on Material Removal Rate

Abstract

The economic efficiency of machining plays an important role in the comparison of alternative procedures in the field of precision manufacturing too. It is not easy to performthe comparison because of the dissimilarities of material removal processes and/or procedures. However, there are some indicators that facilitate the analysis. The paper focuses on the economic comparison of the different finish procedures: grinding, hard turning and combined procedures. We analysed the practical material removal rate and the consumption of the used up coolant and lubricant (CL) as the basis of the operation time of the machining. Compared with grinding, hard turning and combined procedures showed lower operation time and higher material removal rate besides lower environmental load.
