The position detection device is an important part of the CNC machine tool, its function is to detect the displacement and send the feedback signal to compare with the command signal produced by the numerical control device. Photoelectric encoder is a rotary position sensor, widely used in modern CNC servo system for angular displacement or angular rate measurement. At present, most of the CNC machine tools used in production and use are semi closed loop control. Most of the system manufacturers have put the position encoder in the end of the drive motor to indirectly measure the actual position or displacement of the executing parts.
