The results indicate that the ratio between previous work and current analysis in terms of FE simulation is satisfying with the lowest ratio is 75.67%. On the other hand, the manual calculation at an earlier work has different numbers compared to the numerical simulation. However, such results still successfully producing reasonable structural estimations (Francoisa, 2019). 3. Simulation set-up 3.1. Material The aluminum frame typical of Misumi series based on the profile is economy type, high-rigidity type, lightweight type, and standard type. Based on the Misumi specification, aluminum economy type uses the A6063S-T5 aluminum series that converted to the Autodesk Fusion 360 material form with Al3105-H12 based on similar tensile strength of ± 155 N/mm 2 as doing as lightweight type uses A6N01SS-T5 aluminum series converted to Al5052-H34 with ± 265 N/mm 2 or more tensile strength (Misumi, 2019). The standard model uses the A6N01SS-T5 aluminum series converted to Al3004-H34 with ± 245 N/mm 2 tensile strength. The high-rigidity type has 330 N/mm 2 tensile strength, similar to previous work material Al6060 (Caesar et al., 2020). 3.2. Meshing The aluminum structural frame profile is designed to restrain the loads from the static loads of machines and dynamic loads of movement. Acquiring the prime ability, the frame will be tested by the finite element method using Autodesk Fusion 360. The objective of the simulation is to confirm that the loads are distributed to the whole frame and not affected due to bending forces. Fig. 5 presents the four frame part that will be analyzed by the finite element method in Fig. 6.
