Development and Implementation of a Mini CNC Milling Machine

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

A Laser Cutting Machine Prototype

“…In order to perform the laser cutting procedure, one must control the speed and power of the laser diode by using LaserGRBL software, which is widely recognized and performed on mini-CNC machines [18][19][20]. Figure 8 displays the software interface.…”

Akurasi Mesin CNC Router Low Budget Berbasis Mach 3

“…Dalam keadaan kondisi mesin yang baik tentu saja efisiensi mesin yang dihasilkan menjadi terjaga [11]. Fitur-fitur baru yang terintegrasi dikembangkan dalam sebuah mesin CNC, hal tersebut menjadi sebuah tantangan untuk institusi pendidikan dan pemerintahan agar mampu menyiapkan kompetensi pengguna yang sesuai dengan kebutuhan industri serta sarana dan prasarana yang memadai [12], [13].…”

A Customizable Controller for 3 Axis Modular CNC Machine

“…The GRBL programme for Arduino is simple to install and operates straight away to create a low-cost, high-performance CNC controller. G-code is the input signal utilised by GRBL, and an output signal is used by Arduino to control motion [7]. Meanwhile, it has both analog and digital I/O pins which are able to interface with disparate expansion boards, different circuit systems and microcontrollers with other assisted components together to run a program and integrate with various circuits [11].…”
