Prediction of the Cutting Forces on Stainless Steels When Using a Turning Process

Stainless steels have a great application in the manufacturing process especially due to their characteristic high corrosion resistance. The machining of these materials, the study of the cutting forces, and the power required for the cutting are important parameters to be evaluated. Their relationship with other cutting variables process is crucial for the optimization of the machining process. The results of this research are empirical expressions relating cutting parameters (cutting speed, feed rate and depth of cut) to cutting forces for each stainless steel studied, AISI 304, AISI 420 and AISI 420_HT (HT: Heat treated). A general expression was also developed which includes the mechanical properties of these stainless steels. These results enable the user to predict cutting forces when using a turning process.
