  • Patent number: 11820047
    Abstract: The invention relates to an additive manufacturing method in which a component (10, 42, 43, 44, 45) is produced in layers using an energy beam (8, 41, 58) which solidifies a starting material (4) and is irradiated by energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61) while the starting material (4) is held by a base surface (3, 15, 30, 36, 52) arranged on a base element (2, 16, 29, 35, 51). While the starting material (4) is being irradiated with the energy beam (8, 41, 58), the base element (2, 16, 29, 35, 51) is moved by a rotational component which has a base element rotational axis, wherein the starting material (4) is held on the base surface (3, 15, 30, 36, 52) by a centrifugal acceleration generated by the rotational component. The invention is characterized in that a rotational movement is produced for at least some of the energy beam irradiating means (9, 22, 31, 38, 39, 55, 59, 61).

  • Publication number: 20230314118
    Abstract: Strain sensors are attached to a workpiece, and resistance values of the strain sensors are measured with time while cutting the workpiece with a milling cutting machine. A power spectrum in a frequency domain is obtained by Fourier-transforming the resistance values measured with time. A power peak is found in the power spectrum to be outputted as a magnitude of vibration occurring during machining the workpiece. By attaching a strain sensor to a stamper of a plastic working machine, a resistance value of the strain sensor is measured while pressing a workpiece on a die with the stamper. A magnitude of the strain corresponding to the measured resistance value is used to obtain a corresponding plastic working force. By attaching the strain sensor directly to the workpiece, it is possible to monitor the state of the plastic working and/or cutting process of the workpiece with high precision at low cost.

  • Publication number: 20210294044
    Abstract: In a method for aligning a polarization-maintaining optical fiber, in which the optical fiber (7a, 7b, 7c) is held in clamping fashion by means of a clamping device (12, 19, 23), a given rotational position of the optical fiber (7a, 7b, 7c) about the fiber longitudinal axis is detected, and the optical fiber (7a, 7b, 7c) is rotated about the fiber longitudinal axis by means of the clamping device (12, 19, 23), it is proposed that at least one clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 19, 23), said clamping element abutting against the optical fiber (7a, 7b, 7c), is moved relative to at least one further clamping element (13, 14, 20-22, 24-27) of the clamping device (12, 13, 17), said at least one further clamping element likewise abutting against the optical fiber (7a, 7b, 7c), for the purposes of rotating the optical fiber (7a, 7b, 7c). Moreover, a correspondingly configured apparatus is presented.
