An Arduino based 3-axis CNC drilling machine for printed circuit board is implemented using Arduino controller, CNC router and open-source software for controlling the whole operations. This can be the invention for the electronic industries. Using this CNC machine, one will be able to draw a circuit layout on PCB or any other solid surface using simple algorithm and available components. At first, the user needs to design PCB layout using eagle software which is directly generated G-code and then feed it to the machine using candle software. Arduino Uno with an AT mega 328 microcontroller is used as main controller for this system. The microcontroller converts G-code into a set of machine language instruction to be sent to the motor driver of the CNC machine. This system can provide drill in less time and increase the flexibility. For drilling multiple holes in a component basically we use vertical or horizontal drilling machine. Even if these machines are efficient but are not suitable for small scale industry due to its higher cost. Thus, small scale industries suffer a loss due to non-availability of these machines. Also, operational and maintenance cost is higher for these machines. Due to bulky structure of these machines, it occupies more space. 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. To overcome this problem, we need to design machine such that it will perform the function of drilling machine with lesser initial cost and easy in operation. Thus, it will be easily affordable for small scale manufacturers. In this machine we arrange lead screw in X and Y axis for movement of the component on which the drilling operation is to be performed. The idea behind fabrication of low-cost CNC drilling machine is to fulfill the demand of CNC drilling machine from small scale to large scale industries with optimized low cost, smaller size, easily operable, easy interface, flexible and low power consumption.
