Modeling by finite element of a turning process with chip detachment

Abstract

In the present chapter, we have developed mathematical modeling and analysis by finite element (FEA) process of turning with chip detachment; the study incorporated the dynamic and structural cutting orthogonal and oblique mathematical models in three dimensions (3D) and with incorporating thermal mesh structural static fluid for your simulation in FEA software. Validation is performed on an experimental basis by record temperatures and mediated the release of chip in the process of turning with octagonal and oblique cut. With the simulation are determined variables important to optimize; these are orthogonal and oblique cutting: cutting speed, cutting depth, and angle cutting, presenting a variation of 4-8% with respect to the experimental values. In this process, it was determined that cutting temperature presents a value means of 132 °C and a maximum of 147 °C and a minimum of 115-14 °C cutting angle and a forward speed of a 0.1466 speed m/s temperature-optimized cutting. In the process of chip detachment are decisive values for temperature, speed, depth, and angle of cut according to a previous simulation incorporating the models mentioned above.
