This paper presents the work on design and fabrication of a low cost three axis mini portable CNC milling machine; using Arduino Microcontroller, stepper motors and GRBL Shield. The present work is an attempt to minimize the overall cost of the computer numeric control machines while maintaining the accuracy of working. The low-cost machines will help in the skill development initiative started by Indian government for quality work force. This machine will target the budding entrepreneurs/wood workers to create intricate designs on work pieces at minimum investment, as compared to the existing commercially available CNC milling machines; which are very costly and bulky. The intention is to maintain the same output (in terms of accuracy and repeatability) as that of existing large machines while reducing its size and price. The machine is designed by considering various facets of the machine such as aesthetics, reliability, safety, performance and financial value. In this era of competitive markets, this machine will help the workers in rural areas and will play a crucial role in strengthening their manufacturing capabilities and enhancing the economic development of nation.
