Abstract:
A computer-implemented method for forming a three-dimensional workpiece from a block of material using a fluid jet cutting device is implemented by a fabrication system. The method includes receiving an indication of the geometry of the workpiece and generating a three-dimensional tool path to control a cutting head to form the workpiece. Generating the tool path includes receiving an indication of a desired cutting surface on the workpiece, determining a length of the cutting surface, and designating a plurality of waypoints along an edge of the cutting surface. Generating the tool path also includes determining at least one geometric parameter of the cutting surface at each waypoint of the plurality of waypoints, and calculating a speed of the cutting head at each waypoint of the plurality of waypoints based on the determined geometric parameter such that the speed of the cutting head varies along the cutting surface length.
Abstract:
A coating system and a method of applying the coating system on an article. The coating system includes a sacrificial coating on a surface of the article and an erosion-resistant coating on the sacrificial coating, wherein the erosion-resistant coating comprises a layer of a polymeric material. The sacrificial coating is more anodic than the surface or the erosion-resistant coating.
