The Software has been used to produce a G code for the operation of the system. The Arduino plotter machine has been dependent on the principle of Computer Numerical Control with limited area depends on the motion X, Y and Z axes. Basically, the system of this plotter machine is modeling by solid work software to work with three axes stepper motors (as X, Y and Z axes), these three stepper motors are controlled by shield for movement (X, Y and Z axes). This machine’s movement on the X axis is 215 mm and Y axis is 235 mm. Length of travel means the linear movement of stepper motors that control for X, Y and Z axes from point to another point. The left and right movement controlled by X axis stepper motor, front-back movement controlled by Y axis stepper motor and the pen is up-down that is controlled by Z axis stepper motor Key Words: CNC, Arduino, G code, Micro controller unit. 1. INTRODUCTION: Computer Numerical Control (or CNC) is an advanced form of automatic machine that used widely to control the motion of these machine tools. Numerical control machine was first invented around in 19th century to minimize the load of the work. Its advantage ensures higher efficiency, higher flexibility, and low production cost, a little working time and a little loss in production. It mainly follows three steps that are receiving data, interpreting them and react accordingly. To direct the machine function, a special codes and numbers form sequential commands (instructions) that are used to operate the machine automatically and to produce a specific part with specific dimension. These instructions (program) are then converted in to an electrical signal and act as input to the motors which run the machine and do the basic movements. A machine control unit (or MCU) decides the tool depth of draw, drawing speed etc. Motion of tool is based on Right hand coordinate system. Three axis of rotation (x, y & z) for three dimensional motion of tool and for specific role plus an axis of rotation. The x-axis serves as height stands and uses two pieces one for front and one for back. The y-axis acts as motor mount to move z-axis in addition with slide mechanism whereas the z-axis controls the depth by allowing the movement of router in up and down direction so it is very important axis. 2. LITERATURE REVIEW: Various authors have studied the development of such machines. ‘Fabrication of Low Cost 3-Axis CNC Plotter Machine. Venkata Krishna Pabolu et al. Nov 2010: “Design & Implementation of a three Dimensional CNC Machine”. It increases the demand for flexibility and cutting with respect to edge quality. It maintains the accuracy and reliability for complex shapes. In this system they used visual C# as a language on .NET platform. In this there are three main kinds of computerized numerical controllers: 1.Multiprocessor with ASIC, 2. PC front end, 3. Motion control card with PC. The design of this system is user-friendly one which give accurate results and also flexible to users. RTOS is very costlier and not user friendly and also with such system it is not possible to implement on any general PC, where user has to purchase the operating system. Sundar Pandian 2014 : “develop low cost 3 axis CNC machine”. It is low cost and it is used currently in the laboratory. Stepper motors with drivers, Arduino open source, and microcontroller and open source motor control software. Author used ready to assemble kit from Zen Tool works, USA. Kit provided stepper motor, lead screw, guide rod, anti-backlash falans and spring. He made the Body with high density PVC. The machine has fix gantry and mobile bed so there is restriction in working area. The model provides more scope for hands- on learning by the students and therefore better learning outcomes. It is developed for only educational purpose. Kajal J. Madekar, Kranti R. Nanaware, Pooja R. Phadtare, Vikas S. Mane Feb 2016 “Automatic mini CNC Machine for PCB drawing”. To develop low-cost automatic mini CNC machine for PCB drawing. This system reduces the cost of machine and increases the flexibility. In this G code is interfaced with ATMEGA 328. CNC based controller by FTDI module which is used to convert the code in convenient controller the code i.e. serial to USB converter, x moves to left, Y moves to right and z moves to up and down. It gives better accuracy and reduces the work load. G code mark easy to find the
