Dynamical Identification Model of Laser Cladding Height in Metal Parts Laser Shaping Process

Abstract:

The metal parts laser shaping process dynamical identification is fulfilled by the method of experiment. Through step response experiments, mathematical models between the cladding height and the laser power, the scanning speed, or the powder flowrate are established respectively. Simulating experiments validate these identification models. From the identification models, the metal parts laser shaping process is understood, which is the basement for designing closed loop control in forming process and is significant to improve the quality of formed parts.
