Manufacturing by separating particles of material from a solid body by non-mechanical means. Ablation refers both to the removal of layers of material and to the separation of workpiece parts. The production process of ablation is considered in its stationary instantaneous state, independently of the application of auxiliary processes necessary to initiate the process. Ablation is divided into three subgroups according to the order point of view (OGP) "process in the effective zone on the surface of the workpiece": - thermal ablation; - chemical ablation; - electrochemical ablation.
