Abstract – Sometime for make PCB, we required more time for designing, printing, etching as well as drilling. Therefore to reduce time and more effort we are design this project. In this paper, the design of a PCB milling and drilling machine, where the drill holes and the layout are automatically find out from an image of the circuit in EAGLE software. This paper focuses on the design and implementation of automatic PCB milling and drilling machine using ARDUINO UNO. Further the drilling machine uses path planning through co-ordinate measurement machine method which is used to make the system more stable and accurate.
Key Words: CNC, Arduino controller, G-code, PCB, Drill machine, etc.
1. INTRODUCTION CNC Machine is a generally used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include milling, and drilling. The CNC stands for Computer Numerical Control. From this CNC technology, the biggest change in the world of digital electronics & Micro-controller, we are presenting here an idea of CNC bit plotter using ARDUINO UNO. The idea behind this project is to make a small CNC machine which can draw images or pictures on surface which can be a paper or anything. It uses three stepper motors as linear actuators on each axis X, Y & Z. While printing, the proper synchronization of this entire three axis i.e. stepper motors, is most challenging task. At present the data to draw is given programmatically i.e. hardcoded in program in binary format. A bit touches the surface & prints the pixel for logic 1 and lifts up in air for logic 0 & actuator changes it position for next commands execution. As in future plan, it can access the G-Code directly from supporting software like in scale. Presented plotter is one dimensional 1D plotter.
1.1 Design Idea The PCB is placed to this system then it is drilled automatically through path planning. The PC provides X, Y, Z co-ordinates and by using the pc software read the file which is generated by the PCB design software. Another system uses the basic 8051 microcontroller and drilling driver are designed by relays makes system bulky and does not provide Š 2017, IRJET

high amount of current in order to drive the motor exactly. Another method uses microcontroller the c programming. The system consists of three 3 stepper motor and one AC motor to control drill. Thus due this the system is complicated and system becomes instable. The proposed project does not use the path planning method. Further the automatic PCB drilling machine uses a path planning algorithm, which is capable of estimating an exact traversing path for the drill bit. The path planning algorithm optimizes the use of the motors and other mechanical paths involved in the process while reducing total time taken to cross all the drill holes. In this project, the developed software takes the position of the drill hole. Than it calculates the previous and current co-ordinate and sends the coordinate information Microcontroller unit over USB cable. Stepper motors move on the basis of co-ordinate information to accomplish the drilling of the PCB..[1]

1.2 Literature Review Micromachining operations play an important role in precision production industries. Out of the various machining processes, micro-drilling is used to produce micro holes in fuel injectors, printed circuit board, aerospace materials etc. So in order to achieve the optimum working conditions various research were conducted by different researchers from across the globe. This report reviews some of the journal published by them regarding optimization processes. Yogendra Tyagi, Vadansh Chaturvedi and Jyoti Vimal [2] have conducted an experiment on drilling of mild steel, and ISO 9001:2008 Certified Journal
