Abstract
- This paper discusses design and implementation of low cost 3 Axis Drawing Machine using Arduino controller based on computerized numerical controller (CNC) machine and open source software (G-code and GRBL) for controlling whole operation. Computer numeric control (CNC) machine plays an important role in the field of automation. The main aim of this project is to reduce time consumed and it reduces human involvement which eventually reduces rate of error and also increase the accuracy of the production. The communication between the open source software (G-code and GRBL) and hardware (Arduino and CNC shield) is to be done with the help of USB.
P.A. Sherring da Rocha Jr., R.D.S. Souza, and M.Emilia de Lima Tostes [6] have presented a prototype CNC machine under development running on a PC with LabVIEW which has advantage of ease of visual programming tools. The PC is interfaced with low-cost embedded microcontrollers through the serial port. The CNC machine designs above rely on the use of stepper motors of limited power in open loop mode. Xu, Y. Li, J. Sun, and S. Wang [8] discuss results of research on an open CNC system using Windows PC with a four-axis motion controller. A major new development in computer technology is the availability of low-cost open source hardware, such as the Arduino micro-controller platform.[10]
1. INTRODUCTION 1.1 Objectives -
CNC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. CNC – Computer Numerical Control – Taking digitized data, a computer and CAM program is used to control, automate, and monitor the movements of a machine. The CNC controller works together with a series of motors and drive components to move and control the machine axes, executing the programmed motions. Open source microcontroller platform Arduino is used for control of the motors, and open source software is used for executing the G code for machining applications. Several authors have studied the development of such machines on a smaller, low-cost scale. For example, V.K. Pabolu and K.N.H. Srinivas [4] have designed and implemented a three axis CNC machine using an 8-bit microcontroller. The development is in .Net platform using C# programming language on a Windows XP computer, but the motors have limited power. T. Andrei and I. Nae [5] have developed a simpler commercial size CNC router running with Mach3 software on a desktop PC, but requiring a parallel port.

The idea behind the fabrication of low cost 3 Axis Drawing Machine is to fulfill demand of small scale industries. An advantage of open source hardware is that a wide variety of ready-to-use software is available for them on the Web, therefore the prototyping and development times are drastically reduced. Moreover, a wide range of low-cost interfaces, sensors, and accessories such as Arduino shields are also available on the Internet, along with clear instructions, examples, and applicable program code. In this paper, the development of a prototype 3-axis CNC Router using Arduino-based control system is presented with following specifications: • Low cost • Easily operable • Easy interface • Flexible • Low power consumption
