From the previous work (Caesar et al., 2020), the results show that the number of Scenarios 1 has a higher value than Scenario 2 for aluminum 6061 material represent the high-rigidity aluminum frame. This paper will provide the comparison of different aluminum frame for displacement, maximum stress, and safety factor value of the auto checking hardness machine's frame.

Tables 4 to 6 shows the static simulation index of various type. From Sub-section 4.1 Material is explained that the differences in aluminum frame type based on ultimate tensile strength converted with Autodesk Fusion 360 material library. The previous work (Caesar et al., 2020) used a high-rigidity aluminum frame type and had the most significant material properties of tensile strength, i.e., 310 MPa. Cross-sectional area properties also reinforce it (see Fig. 1). The high-rigidity aluminum frame also has the most significant cross-sectional area than the other aluminum frame. The second type is a standard type that has 265 MPa tensile strength value. The third type is a standard type that has a 245 MPa tensile strength value. The last one is the economy type that has the smallest value of tensile strength, i.e., 155
