This independent project, conducted by Industrial Engineering students at Universitas Atma Jaya Yogyakarta, focused on the design, fabrication, and testing of a custom CNC Milling Router. Aimed at supporting professional learning in the era of Industry 4.0, the project provided hands-on experience with CAD/CAM technology, team collaboration, and the practical application of industrial automation concepts.
The methodology followed a structured process beginning with project planning, task division using RACI matrices, and detailed scheduling via Gantt charts and a Work Breakdown Structure (WBS). The team designed the machine using SolidWorks, creating 3D and 2D models, and specifying components like an aluminum profile frame (1000x1000x1000 mm), NEMA 17 stepper motors, and a 24V DC power system. The fabrication phase involved step-by-step assembly of the frame, mechanics, and electronics, culminating in a fully assembled CNC router.
Testing was carried out to evaluate machine functionality, axis movement (X, Y, Z), and sensor integration, such as thermal protection for the spindle. A lotus flower design was created in SolidWorks, converted to G-code via CAM software (Mach3), and successfully milled, demonstrating the machine’s operational capability. Although some challenges were noted with material flexibility affecting surface finish, the project successfully achieved its core objectives.
In conclusion, the project enabled students to gain comprehensive skills in CNC machine design, assembly, electrical systems, and software operation. The final product is a functional CNC Milling Router that transforms CAD designs into machined parts using G-code, supporting future educational and prototyping activities within the university.
