FEA Analysis Of The Lathe Machining On Machining Characteristics Towards Aluminium Alloy Using RSM Method
This project focuses on the simulation of the turning process by using the finite element analysis (FEA) machining Deform 3D software based on the Box-Behnken of response surface method (RSM) experimental matrix. Based on the Box-Behnken design matrix, there were 13 simulation runs with one centre p...

In the meantime, the interaction between cutting speed and feed rate is the major interaction that gives the most influential impact on the effective stress, which shows that the effective stress increases with the increase in both of the cutting speed and feed rate. The most influential interaction that gives a significant effect on the material removal rate is the interaction between feed rate and depth of cut, which shows that the material removal rate increases with the increase in both of the feed rate and depth of cut.
