Dr. Sandeep M. Salodkar
Abstract
Finite element methods (FEM) based modeling and simulation of machining processes continues to captivate researchers, offering a pathway to enhance understanding of chip formation mechanisms, heat generation in the cutting zone, tool-chip interfacial frictional characteristics, and surface integrity of machined components. To delve deeper into these aspects, a chromel K-type thermocouple was employed to measure cutting temperature at the tool-chip interface during the turning of En31 steel. In this research endeavor, a temperature measuring setup was meticulously designed and fabricated. Utilizing this setup, the generated temperature was accurately measured during the turning process of En31 steel, and the findings are comprehensively reported in this article. Subsequently, leveraging the insights gleaned from the experimental results, a two-dimensional simulation model for orthogonal metal cutting operations was developed using the software ANSYS. This simulation model facilitates the visualization of various temperature distribution plots, elucidating the effects of different cutting parameters on the generated temperature through distinct graphical representations. By offering a detailed understanding of temperature distribution at the tool-chip interface, the developed model serves as a valuable tool for predicting cutting temperature dynamics during turning operations, thereby contributing to advancements in machining process optimization and efficiency.
