In the current context, automated control systems play an essential role in enhancing the productivity and flexibility of production lines. Particularly in fields such as precision mechanics, CNC machining, and industrial robotics, the simultaneous and accurate control of multiple motor axes is a decisive factor in product quality. AC Servo motors are widely utilized in motion control systems due to their exceptional capability to control position, speed, and torque with outstanding precision. Achieving synchronous control of multiple servo axes—especially for complex interpolation tasks—requires a system with fast signal processing, low latency, and highly stable communication. Mitsubishi's SSCNET III, a high-speed communication network dedicated to servos, effectively addresses these requirements by seamlessly connecting multiple servo axes to a central controller. This paper presents an experimental study on a 3-axis interpolation model integrated with Programmable Logic Controller (PLC) and Human-Machine Interface (HMI) technologies. This integration aims to automate operations and alternate the operation of the lead screw axes, enabling system monitoring without the need for manual or semi-automatic intervention. Based on experimental and evaluation methods, the research demonstrates the potential to enhance the accuracy of interpolation control.
