Controlling of a mechanical system having three dimensional moving capability by using servo motors, FPGA and a personal computer

CNC machines are controlled by a computer mounted on CNC. Fast interface tools are required for the synchronization between the PC and servo motor drivers. That is one of the important problems of CNC technology. The control of system based on FPGA together with a computer will contribute to studies on the subject and will increase the level of information on this subject. The major goal of automation in manufacturing facilities is to integrate various operations in order to improve the productivity, increase the product quality and uniformity, minimize the cycle times and effort, and reduce the labor costs. Since 1940s, automation has accelerated because of the rapid advances in control systems for machines and in computer technology. CNC machines are imported mostly in our country. The studies on this subject will contribute to increase the national technology so the economy. This study will contribute to increase the speed, flexibility and control knowledge of the CNC machines in our country. The communication between the computer and the FPGA is provided. The data is processed on the computer with a graphical program. This data can display on the computer screen in both graphical and numerical. These data could be used for statistical analysis. The selected FPGA is connected to the computer and operate together to generate required control signals for the servo motors.Controlling of the three axes of servo motor smoothly and flexibility using FPGA is achieved in this study.
