Abstract: An end mill cutter (1; 100) includes a shaft (10) and a cutting head (20) with a number of helically running cutting webs (50), which are spaced apart from one another by means of flutes (30). The cutting webs (50) are divided into cutting web segments (60) at least over a portion of their length by a number of divider grooves (40) running helically in the opposite direction. The cutting head (20) is divided into a shaft-side cutting step (22) and an end face-side cutting step (24) adjoining the shaft-side cutting step (22) via a transition section (23) with a cutting diameter, which is smaller with respect to the shaft-side cutting step (22).

Abstract: The invention relates to a method for producing a cutting tool comprising the following steps: a) providing a starting material for use in an additive manufacturing method in a plurality of material layers; and b) bonding each material layer of the starting material in the form of an indexable insert, wherein the material layers are arranged such that a recess is formed in the cutting tool for securing the cutting tool with a fastener to a tool base body in order to secure the cutting tool with a tool reference level that is parallel to a support plane of a tool base body.

Abstract: The invention relates to a method for assembling a tool system module, having a main body (G3C), which comprises a standard shank, such as a hollow-shank-taper (HSK) shank, and having a functional section (F5Y), such as a tool holder. In order to produce such tool system modules particularly economically, the functional section (F5Y) is paired with a main body (G3C) that is produced on separate production line, which is independent of the design or the production line of the functional section.

Abstract: The invention relates to a multiple edge drill such as is especially used for machining difficult-to-machine, e.g. high-toughness materials, such as e.g. cast steel, steel for hardening and tempering or other difficult-to-machine steel materials including metallic cast materials, such as e.g. gray cast iron, and especially GGV or ADI cast iron. The facet is designed in such a manner that the main cutting edge has at least two main cutting edge sections that define point angles of different size, the radially outer point angle being smaller than the radially inner one, thereby obtaining a good cutting behavior and long service life of the tool.

Abstract: A method and system for conducting semantically weighted searches in a governed corpus of terms is provided. A search expression having a plurality of terms for performing a search in the governed corpus of terms is received. The governed corpus of terms comprises a plurality of corpus expressions each comprising a plurality of terms, each term within the governed corpus of terms being associated precisely with a single concept within a lexical database. At least one concept of the lexical database is assigned to each term in the search expression based on a syntactical analysis. A semantic similarity is calculated between pairs of concepts of the search expression and one of the corpus expressions. A total semantic similarity is calculated between the search expression and the one of the corpus expressions by aggregating the semantic similarities of the pairs of concepts based on an order of significance of the terms.

Abstract: Methods and systems are described that involve rule-based vocabulary assignment of terms to concepts. Instead of assigning individual terms to each concept in a conceptualization of a domain, such as taxonomy, ontology, and so on, production rules are defined and assigned to each concept. The production rules produce at least one term to name a concept by referring to semantically related concepts to this concept. The production rules may include context information specifying the context where a given rule is valid. The methods and systems can be used to improve search capabilities for entities by enabling easier annotation of large conceptualizations. Further, the methods and systems can improve user experience by allowing context specific naming of entities.

Abstract: Described herein is a method for Global Data Type (GDT) ontology generation that involves parsing GDTs in order to define their basic components and building hierarchical structures for each GDT basic component. Each hierarchical structure is created by breaking down the corresponding GDT basic component into semantic elements and defining a relation between the elements, allowing easier navigation through the structure. New semantically compliant GDTs can be composed by combining already existing elements from the defined hierarchical structures. The GDT ontology eases GDT searching and simplifies the process of creating new GDTs.

Abstract: A shrink-fit chuck tool holder for cylindrical, particularly circular cylindrical, shank tools, including a fastening shank for establishing connection to a machine tool and a thermally expandable shrink section. The shrink section has an inside recess for accommodation of a tool shank and a pre-positioning section, which precedes the recess via a step and has an axial extension. The pre-positioning section is disposed eccentrically to the inside recess.

Abstract: The invention relates to a shrink-fit chuck tool holder for cylindrical, particularly circular cylindrical shank tools, comprising a fastening shank (12) for establishing the connection to a machine tool and a thermally expandable shrink section (14). The section has an inside recess (16) for the preferably centered accommodation of a tool shank (22) and a pre-positioning section (20; 120), which precedes the recess via a step (18; 118) and has a small axial extension (EA), characterized in that the pre-positioning section (20; 120) is disposed eccentrically (E/2; (E1+E2)/2) to the inside recess (16; 116).
