Automatic calibration of a measuring circuit
11402244 · 2022-08-02 · ·

The present invention describes an automatic calibration method for a measuring circuit for example in an industrial automation or handling process, where only one person is needed to manage the entire procedure. The components are a calibrator (11) which the worker in the field has with him, which can be connected to the starting end of the measuring circuit in order to give an impulse. The quantity to be measured/calibrated has not been limited. The measurement result is seen at the end of the measuring circuit on a screen of the control room, i.e. DCS (13). Depending on the alternative embodiment, the measured numerical value can be steered either to a dedicated server (14) over an OPC connection, and onwards wirelessly or via Ethernet back to the calibrator (11). One alternative is to use a smart device (16) which the worker has, with suitable applications, to which the measured data can be sent over a network, and the data is also presentable in a user-friendly manner in such an application. Thus, the data can be sent onwards to the calibrator (11) in the field over a BT connection. A third alternative is a direct sending of the measurement result from the control room (13) to the calibrator (11), whereby a 3G/4G/5G network, a Wifi, Bluetooth or Ethernet connection can be used for sending the data. A delay module (15) manages mutual temporal synchronization of the data i.e. numerical pairs. The data can be stored in a spreadsheet, matrix or graphic form in a desired place, such as in the calibrator's (11) own memory or in a desired server for example in a cloud.

20210114167 · 2021-04-22 ·

The invention relates to a grinding and/or erosion machine (10), as well as to a method for gauging and referencing the axis arrangement (11) comprising several machine axes (12), wherein each can be configured as a rotational or translational machine axis. To do so, a measuring disk (28) is inserted in a tool spindle (13) and a test mandrel (27) is inserted in a workpiece holding device (14). The test mandrel (27) is electrically connected to a reference potential, preferably ground (M). The measuring disk (28) is electrically connected to a supply voltage potential (UV). By forming a contact between the measuring disk (28) and the test mandrel (27), a measuring current (IM) flows between the supply voltage potential (UV) and the reference potential and, in accordance with the example, from the supply voltage potential (UV) to ground (M). The flow of this measuring current (IM) may be detected in a monitoring device (31), and the actual position of the machine axes (12) at the time of the start of the current flow of the measuring current (IM) can be determined. Via the axis arrangement (11), one or more contact locations (K) between the measuring disk (28) and the test mandrel (27) can be approached, and, as a result of this, referencing or gauging of the axis arrangement (11) and the machine, respectively, can take place.
