Abstract

This state of knowledge addresses the teaching of Computer Numerical Control (CNC), a fundamental technology for modern manufacturing, and the challenges faced due to the high costs associated with the acquisition and maintenance of CNC equipment. The objective is to systematically review the existing literature on the topic, focusing on the technological solutions proposed to overcome these financial barriers and improve the teaching-learning process. The author conducted a comprehensive review using databases such as IEEE, CAPES Journals Portal, and BDTD, selecting relevant studies on virtual simulators, augmented reality applications, online platforms, and low-cost CNC machine development projects for educational purposes. The analysis of these works highlights the need for a free, innovative, and fully didactic platform to efficiently teach CNC programming. Existing simulators, while providing a virtual experience, lack efficient pedagogical resources to assist students in understanding fundamental concepts. Furthermore, many of these simulators require prior knowledge, hindering the learning process for beginners. The state of knowledge emphasizes the importance of overcoming cost and access barriers by offering a solid pedagogical approach, specifically designed to teach CNC programming intuitively and gradually, guiding students from basic concepts to the creation of more complex programs, providing interactive resources, practical exercises, and constant feedback.
