Abstract
Laser chemical machining (LCM) is intentionally limited in its removal rate to avoid disturbing boiling bubbles in the process fluid. To overcome this limitation, an enhanced material removal model is required based on surface geometry and temperature in-process data. For this purpose, fluorescence measurements and confocal microscopy are combined to enable in-process experiments in LCM environment. Derived from fluorescence effects, the geometry and surface temperature are indirectly determined under LCM-equivalent conditions such as thick fluid layers and gas bubbles in the beam path.
