A NOVEL TECHNIQUE FOR CONTROLLING CNC SYSTEMS BY USING ARDUINO

electonics and communication engineering

This paper improves the performance of the existing micro Computer Numerical Control (CNC) machines. In this paper, (1) a single axis (vertical axis) CNC machine and (2) a two-axis CNC machine (X-direction and Y-direction) are re-fabricated to improve their robustness and reproducibility. The prototype CNC Machine tool is procured from the manufacturer of CNC Machines for performing the work. The Atmega 2560 microcontroller used in this work is provided with Arduino development board environment for designing the control unit. Three unipolar stepper motors are used for controlling the machine axes. First part contains the work carried out in the design of single axis CNC machine (Z- Axis), and the second part contains the design of a two-axis CNC machine (X-direction and Y-direction). Improvised Stepper motor drivers were designed to improve the robustness and factors related to power dissipation. The traversing time of the drill bit of the drilling machine is considerably reduced by appropriately re-designing to reduce its response time. Sophistication of the twoaxes machine was done to facilitate working in program mode by providing to the use number of ports in the microcontroller. Using the newly designed stepper motor drivers in this CNC machine, the run time operation in program mode of the machine has been enhanced. While the single axis machine is used to drill holes, the two-axis machine moves a platform on a XY-plane (2-Degrees of Freedom) in different geometric patterns/paths.
