Abstract

The invention relates to a method for machining a workpiece (0, 0') into a piece good (1, 1') in multiple machining processes (Bj) using a machine tool (10) with multiple tools (12j). In each machining process (Bj), the tool force (F) exerted onto the workpiece (0, 0') is measured as a chronological sequence of measurement signals (Sj) by means of a piezo electric force sensor (14), wherein in a learning phase (V1, V2, V3, V4), a first workpiece (0) is machined, a quality feature (Q) is checked, and an accepted-part characteristic (GKij) is ascertained and is classified into an accepted-part class (GCj); and in a subsequent phase (V5, V6, V7), another workpiece (0') is machined, and a piece good characteristic (SKij) is ascertained and is classified into the accepted-part class (GCj). Thus, a first workpiece (0) is identified as an accepted part and is classified into an accepted-part class, and for a subsequently machined workpiece (0'), the workpiece characteristic (SKij) is used to ascertain whether the subsequently machined workpiece is classified into the accepted-part class (GCj) without needing to check whether the additional piece good has the quality feature (Q). The classification of the piece good characteristic (SKij) into the accepted-part class (GCj) is used to automatically arrive at two conclusions as to whether the additional piece good is an accepted part or a rejected part and whether required tools are worn or not, and if so which of the required tools are worn.

Abstract

A method for generating a calibration function of a WIM sensor that is arranged in a roadway and measures a wheel force exerted on the surface of the roadway includes recording the roadway's road profile. A wheel force is determined by a simulation. The simulation is used to determine the dependency of the wheel force on the road profile for at least one position of the road profile that has been recorded in the first step. The dependency is used to minimize the influence of the road profile on the measured wheel force of the WIM sensor.

Abstract

A hollow profile for a WIM sensor elongates along a longitudinal direction and includes a plate-shaped force introduction element, an anchoring element and a tubular element disposed between the force introduction element and the anchoring element. The tubular element is integrally connected to the force introduction element and to the anchoring element and encloses a first cavity. The anchoring element encloses at least one second cavity. The anchoring element, tubular element and force introduction element are formed integrally with each other.

Abstract

The invention relates to a method for determining the installation depth (58) of a sensor (4) in a test body (2) which has a longitudinal bore (21) that is delimited by an inner wall (28) in the radial direction. A physical measurement variable is present in the longitudinal bore (21), and the test body (2) has a radial bore (22) which reaches the longitudinal bore (21). The sensor (4) is installed into the radial bore (22), and the physical measurement variable can be measured by the installed sensor (4). The radial bore (22) has a radial shoulder (24), and the sensor (4) has a seal shoulder (44) by means of which the installed sensor (4) rests directly or indirectly on the radial shoulder (24). The invention is characterized in that a core depth (26) is ascertained which is the shortest radial distance between the radial shoulder (24) and the inner wall (28), a front depth (46) is ascertained which is the shortest radial distance between the seal shoulder (44) and the end face (48) of the sensor (4), and the sensor (4) is installed into the radial bore (22) such that the end face (48) of the installed sensor (4) lies at the same installation depth (58) as the inner wall (28).

Abstract

A method for mounting a Weigh-In-Motion (WIM) sensor in a roadway that includes a surface layer and a base layer directly adjacent to the surface layer includes making a groove that extends down to the base layer of the roadway. The WIM sensor is inserted into the groove, and then grout is poured into the groove onto the WIM sensor. A WIM sensor for being embedded in a groove beneath the exposed upper surface of a roadway includes a force introduction flange with an upper surface and having a lateral surface connected by an edge to the upper surface so that the lateral surface is disposed at an angle with respect to the upper surface.

Abstract

A method of using a measuring system for detecting a measured physical variable pertains to measuring systems that include a plurality of transmission members forming a measuring chain for detecting the measured physical variable and in which transmission members that are immediately successive in the measuring chain are in a cause-and-effect relationship to each other. The method includes the steps of: a) specifying the measured physical variable to be detected; b) using a computer to compile several measuring chains that include transmission members necessary for the detection of the specified measured physical variable; c) determination of performance criteria of the compiled measuring chains; d) using the determined performance criteria to assess each of the compiled measuring chains; and e) identification of a measuring chain that best satisfies one of the performance criteria determined.

Abstract

A communication system includes data generation units that generate data and a plurality of data evaluation units physically separated from the data generation units and connected to the data generation units via a non-proprietary network. The data evaluation units evaluate data transmitted by the communication system, which includes a hardware abstraction layer that represents a data evaluation unit as a resource that includes a property “data transmission type.” The property “data transmission type” is “Streaming” or “Bulk Upload” or “Streaming, Bulk Upload”. The communication system reads the property “data transmission type” and accordingly transmits the generated data to the data evaluation unit in accordance with the read property “data transmission type”.

Abstract

The invention relates to a pressure sensor, which can be installed in a mould part, for example an injection mould, from a pressure-measuring side. Setting an appropriate amount of recess in the injection mould is simplified thereby and the installation of the pressure sensor in the injection mould is also simplified. The pressure sensor has, at the sensing end, an expanded region, measured perpendicularly to the longitudinal axis of the pressure sensor, which expanded region is greater than or equal to all other expanded regions along the longitudinal axis, measured perpendicularly to the longitudinal axis. A further aspect of the invention relates to an injection mould having the pressure sensor according to the invention. The invention further relates to a method for installing the pressure sensor according to the invention in a mould part, for example in an injection mould.
