It requires a lot of hands-on experience to learn how to operate a computer numerical control (CNC) mill. Virtual Reality (VR) can serve as a way to teach how to properly operate it. The goal of this research is to create a virtual CNC mill that can provide interactive training for students. The Unity software was used for this goal. Unity is a game development engine used to produce video games, utility software, and more. The functionality of the CNC simulation was created with C# scripting. The visual representation of the CNC mill was built through 3D modeling, and then transferred into FBX 3D models which are compatible with Unity. The virtual machine is able to take G-code inputs via either an input field or a text file. For the current version, it can simulate G00, G01, and G02/G03 commands and is able to cut sample workpieces per input. It also can save the coordinates of the cutting path via json file and use a python script to view its movement on a line graph. The virtual machine emulates the input commands very similar to the actual machine. This can serve as a good learning tool for CNC machine operators. The virtual machine created through Unity is proof that a digital simulation is achievable for the CNC machine. Future research will include implementing and incorporating mixed reality. Incorporating these kinds of technology will help a more immersive learning experience for students.
