LASER MACHINING APPARATUS: abstract simplified (18020624)

• This abstract for appeared for patent application number 18020624 Titled 'LASER MACHINING APPARATUS'

Simplified Explanation

The abstract describes a laser machining apparatus that includes various components such as an actuator, a control unit, a machining state observation unit, a feature extraction unit, and a correction quantity calculation unit. The apparatus is used for laser machining processes and is capable of adjusting the relative positions of the machining head and the workpiece. The control unit controls the laser oscillator, machining head, and actuator based on a machining parameter. The machining state observation unit detects light intensities in different wavelength bands using optical sensor signals generated from the workpiece. The feature extraction unit extracts features from the correlation between the optical sensor signals and from individual sensor signals. The correction quantity calculation unit determines the correction parameter and the correction quantity for the machining parameter based on these features.
