Design and Implementation of Three-Axis Cost Efficient CNC PCB Milling Machine

The need for Fabricating a circuit is enormously increasing in day to day electronics. Many resource poor countries in the Developing world are affected by highly expensive commercial PCB milling machines. Hence a low cost and a semi-automated CNC (Computer numerical control) controlled PCB milling machine is proposed.A cost-efficient PCB machine will be designed and developed for the fabrication of both single and double-sided boards with through holes and surface mount technology. The machine will be using commercial, inexpensive hardware components and open source software adapted and improved for future electronics education. Hence future enhancement of the proposed design will be possible. This machine will be used to fabricate PCB boards of size and thickness of 0.2-3.175mm. In future, this machine can be used by the students to fabricate the PCB's at low cost for their mini projects, UG/PG projects wherever required.
