Abstract: A milling tool has a cutting edge geometry with a main cutting edge, a cutting corner, optionally with a bordering planar cutting edge segment, and a secondary cutting edge. The tool is used for milling to achieve the smoothest level surface possible parallel to the rotational axis of the milling tool. Each main cutting edge is formed to result in a generatrix of the envelope curve described by the rotation of the milling tool that has a first outwardly curving segment and a second inwardly curving segment. The first segment increases in its distance from the rotational axis from the beginning of the segment to the end of the segment. The distance of the second segment decreases from its beginning towards its end. The tangents at each point of the second segment encompass an angle ?2 of more than 0° and up to 3° with a parallel to the rotational axis.

Abstract: Computer-implemented methods, computer systems and computer program products are provided for creating and processing a browser compliant human interface description. A predefined application specific human interface description using application specific layout elements is transformed into a standardized human interface description using basic layout elements. The standardized human interface description is decomposed into a human interface layout template and a data description. A data instance is instantiated from the data description. The data instance is merged with the human interface layout template into an individual browser compliant human interface description, which is then rendered to prompt a user for data input. The received data from the user are stored in the data instance. The status of at least one layout element is either stored in the data instance or in a runtime-copy of the standardized human interface description.
