Multiple LAMM tests are performed on these materials with 100 μm diameter endmills at various laser powers. A 3D thermal model is used to quantitatively analyze the material temperature increase due to laser heating during the LAMM process. Finite element (FE) models are developed using ABAQUS to simulate the continuous chip formation, and strain gradient constitutive material models are implemented to model the size effect. The quasi steady-state workpiece temperature after multiple milling cycles is analyzed with a heat transfer analysis based on the chip formation analysis and thermal model simulations. The modeling results in temperature, force and cutting stress are discussed and compared with the experimental results.
