Three-Dimensional Finite Element Analysis of the End-Milling Process in Machining AISI 1045 Steel

End milling is a process that is widely used for producing components in aerospace applications, automobile applications, and many other fields. It is crucial to forecast a workpiece’s deformation behaviour during the machining process to choose the best process settings and maximize the part’s overall quality. Understanding the behaviour of each workpiece during the end-milling process through physical experiments is critical, but expensive. Hence, it is inevitable that a numerical study will be developed to estimate workpiece deformation with higher accuracy and less computational cost. The end-milling process on AISI 1045 is simulated in this work using a 3D finite element modelling technique. The ANSYS Workbench 2020 R1 is used to conduct an explicit dynamic analysis in the suggested model. The workpiece’s stress and deformation values throughout the machining process are estimated and examined.
