Abstract:
The development of mechanical processing machines with integrated CNC systems allows the manufacturing industry to produce complex products quickly with high quality. CNC has become a main course for mechanical students in technical and vocational universities. CNC machine training is required to enhance student's skills to learning in design and manufacturing technology. However, the cost to buy a CNC machine is not cheap. In a developing country like Vietnam, along with the limited budget of most universities, this is an obstacle for students to have the opportunity to use CNC machines. To help students have a teaching aid in learning, improve practice capacity. The article proposes an alternative to design and manufacture a simple, inexpensive milling machine with all the required functions. The CAD models design of the machine model structure were done using Solidwork and NX software. Most of the machine's parts are manufactured and assembled in the Faculty of Engineering Mechanics and Automation laboratory of Engineering and Technology, Vietnam National University Hanoi. The study's main objective is to propose a process for designing and manufacturing a mini vertical 3-axis CNC milling machine with low cost but full features similar to an industrial CNC machine. The machine model introduced in the article can be used as a teaching aid, improving practical capacity for students of machine building.
