The study aimed to design an automated PCB drilling machine which consists of two main parts, the software which is installed in the computer and the drilling machine itself. The coordinates for holes were generated by Eagle software as a text file. The file was then imported into the software, converted to the number of steps needed by the motor and sent to the machine via UART connection. To move the drill to the specific location, three stepper motors were used with an open loop design as its control system. The functionality of its features was evaluated using descriptive approach, and was then analysed and interpreted to show how the project performed. The researchers concluded that the machine was satisfactory in executing its task. However, certain features still need improvement in order for the machine to be more efficient.
