DEFINITION

Classification: 205/649

Eroding workpiece to match nonplanar surface shape of tool electrode:

(under subclass 646) Process in which the workpiece is eroded to match the surface shape of a tool electrode having a nonplanar machining surface (e.g., a tool electrode having a concave surface is used to erode a workpiece until it possesses a convex shape with the same radius of curvature as that of the tool surface, etc.).
