Omid Ghahraei Department of Mechanical Engineering, Isfahan (Khorasgan) Branch, Islamic Azad University, Isfahan, Iran Behzad Bahraminejad Center for Advanced Engineering Research, Majlesi Branch, Islamic Azad University, Isfahan, Iran Journal Article 2024 02 18 A ubiquitous device-widely used in many industrial applications is Computer Numerical Control (CNC) machinery. CNC controller constitutes the main part of a CNC machine, which performs the task of controlling and navigating the tool and implementation of industrial processes. Although there have been many controllers, designed and used, in CNC applications in recent years, most of them experience some limitations and disadvantages towing to the design techniques. This project aims to design and fabricate an innovative Multi Axis Automatic Controller (MAAC) to be used in CNC machinery, which has much superiority over the existing controllers and provides an ideal performance. The MAAC has a closed-loop control system, which can control and drive stepper motors, servo motors, DC motors, and hydraulic and pneumatic movement systems. An Improved accuracy and repeatability within rapid implementation of industrial process could be achieved by using of the MAAC in different CNC applications.
