SAŽETAK /ABSTRACT:

The modern manufacturing industry heavily relies on complex CNC machining systems, where any programming error can lead to costly damage to the tool, the machine, or result in scrap. This paper presents the development and application of a Virtual Machine Tool (VMT) as an effective tool for advanced G-code verification and education. The virtual model can faithfully reproduce the geometry, kinematics, and control of a real machine. Through the integration of CAD/CAM systems, specialized simulation software, and open architecture control systems, a methodological approach for program verification is presented. This approach utilizes toolpath simulation, material removal simulation, and the simulation of the virtual machine tool’s operation according to a given program. In addition to its application in the real manufacturing sector, the paper particularly emphasizes the educational component: VMT provides students, operators, and engineers with a safe environment for learning, experimenting, and mastering complex CNC programming concepts without the risk of physical crashes or damage. The results show that the implementation of the virtual model significantly reduces production preparation time and improves the efficiency level of the educational process
