Abstract
The utilization of Computer Numerical Control (CNC) machines in several industries are very popular for years due to the rapid growth of advanced technology. But, CNCs are inaccessible to vast communities especially students as these machines are bulky as well as expensive. The present project aims to deal with the fabrication of an automatic mini-CNC milling machine that can move in all three directions and can able to drill holes on PCB (Printed Circuit Board), wood, plastic, and other soft materials at an affordable price. The design used here is incorporated with an Arduino controller and a G-code sender library for system operation. It is also reported on the work that the qualitative development of the electronic equipment to operate a mini-CNC milling machine along with its related software. Here an attempt has been made to develop a simple three-axis mini-CNC milling in a cost-effective way, especially for educational purposes and it will also allow future research to improve process performance of different machining operations like drilling, slot cutting, etc.
