Industrial CNC milling machine is huge in volume, complex in structure, poor in system openness and expensive in price, which increases the cost of training relevant professional and technical personnel in enterprises and schools, and restricts the further development of CNC milling machine. In order to solve this problem, based on the existing domestic CNC milling machine and previous research results, this paper designs a teaching type micro CNC milling machine with high integration, low cost, convenient handling, simple structure and high flexibility, and carries out processing experiments on the micro CNC milling machine. The experimental results show that when the spindle speed is 5000 r/min, the feed rate is 2000 mm/min and the engraving cutter is 1 mm, the machining error of the teaching type micro CNC milling machine is 0.1 ~ 0.2 mm, can well reflect the shape of the object to be processed, can meet the students' understanding and learning of CNC machine tools, and meet the needs of carving enthusiasts, in order to make contributions to the further development of CNC milling machines in China.

The development of industrial technology can help the manufacturing industry for producing quality products. One tool that can help produce such quality products is CNC machines. As we know that the price of CNC machines is not cheap. Therefore, in this article, the researchers suggest how to design a prototype CNC laser engraving machine for the acrylic workpiece. The machine is designed as cheaply as possible but provide great benefits. The machine frame is designed using aluminum extrusion, the laser uses a laser diode type, the actuators of axis uses the stepper motor, and the control software uses a USB CNC controller. The dimension of workpiece that can be machined is 600 mm x 300 mm x 2 mm. The optimization of the stepper motor movement system is chosen 1/8 micro stepping after testing full-step method, half-step, 1/8 micro stepping, and 1/16 micro stepping. Using a 2.5 watt diode laser module, the radiant heat received by the acrylic workpiece during the engraving process is 558.8 x 10-5 cal/sec.

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

Abstract For precise job manufacturing, system should possess good dimensional accuracy and surface finish. In applications like drilling, punching, marking, boring, tapping work piece is positioned firstly and then cutting tool performs its action while motion axes are kept stationary. In traditional approach for such applications, manufacturer uses highly expensive CNC machine for programming job cycle and executing the same. Big scale manufacturer can afford such highly expensive machines but for small scale mechanical job manufacturing industry we have to think of low-cost solution that can deliver high class output. In this project we are trying to propose low-cost design which gives similar functionality as that of high-cost CNC machine. By applying this machine in industry, it can acquire the multi generation brief time. In order to perform some operation which requires continuous cutting over a pre-defined curve, CNC machines are used as the traditional machines in the industry. Installation of a CNC machine requires a high financial investment and a skilled labour to perform the different operations on the machine. Apart from that the maintenance cost of such machine are also high. In small scale industries where the operations are performed on small job pieces, the installation of such high-cost CNC machine is very difficult; hence this project work is taken up in which a low-cost CNC laser cutting machine is designed using the Arduino. This CNC laser cutting machine will be quite useful for small scale industries where the job size is not very large. Also, the machine does not require a highly skilled labour to perform operations.
