Analisis Struktur Mekanik Pada Mesin 3d Printer (Cnc Hybrid 3-Axis) Menggunakan Software Autodesk Inventor 2018
ABSTRACT
The automation machine technology has been widely developed to help overcome
the problems in manufacturing performance. One of the developed machines were
the 3D Printer machine that can be used in various professional work fields. One
of the machines developed by Riau University students is a 3D Printer machine
called the CNC Hybrid 3-Axis Machine. However, there has been no research to
examine whether this machine is safe to operate. Thus, the author took the
initiative to determine the quality of the mechanical structure on the machine
frame. Structural analysis studies and determines the effects of loads on physical
structures and their components. The method used for the research on the
mechanical structure of this machine is through manual calculation analysis and
finite element method analysis using the Autodesk Inventor 2018 application.
Each analysis is carried out on every part of the machine that experiences
movement in the direction of the X-Axis, Y-Axis and Z-Axis parts, the frame and
the machine legs. Through the results of the analysis, it can be seen that the
maximum stress that occurs in the X-axis slider frame is 30.687 MPa from
manual calculations and 29.81 MPa from the Autodesk Inventor simulation. The
maximum deflection value occurs in the engine frame and the largest maximum
deflection value occurs at the slider of X-Axis with a value of 0,3543 mm. By
comparing the results of manual structural analysis and finite element analysis
simulations, it can be seen that the structural frame has a safety factor value
above 15 so it is safe to use and operate in the future.
Keywords: CNC Hybrid 3-Axis, Structure Analysis, X-Axis, Y-Axis, Z-Axis.
