Identification of process domains in cutting

Summary form only given. Laser cutting is an established separation process. Reliable machining at high productivity and quality as well as simplified machine operation are the actual goals. Monitoring and control of the dynamical process is investigated. This work describes the advances in fundamental physical modeling of time dependent processes such as piercing and contour cutting. Singular perturbation and spectral methods are applied to reveal the number and type of characteristic dynamical variables. Refinement of the dynamical model is performed in order to identify the relations between phase space dimension of the model, properties of the monitoring signals and the quality features of the process. As result the dynamical properties of the process are mapped to different domains of the processing parameters.
