Laser engineering – Motion control design for laser micro-machining

understanding the axis motion control in laser system

In laser micro-machining, axis controls define precision and speed. Five-phase stepper motors offer micron accuracy via microstepping, ideal for point-to-point drilling in semiconductors. Voice coil actuators deliver >100G acceleration for sub-micron optical alignment and laser trimming. Piezoelectric stages provide nanometer resolution with sub-ms response, perfect for maskless lithography, though limited to short travels.
Hybrid systems combine coarse (steppers for long-range) and fine (piezo/FSM for beam steering) actuators, compensating vibrations with adaptive optics for >50nm stability. Real-time firmware enables predictive motion algorithms, ensuring repeatability in dynamic setups.
Applications span wafer processing, medical device etching, and aerospace trimming, boosting efficiency with vibration immunity and no backlash. Emerging tech like magnetic levitation and AI optics further enhance multi-DOF control.
