Patent number: 11204600Abstract: A data interface device for data transmission between a numerically controlled machine tool and external data processing device, including: a control interface unit for data transmission with a control device of the machine tool and communications unit for data transmission with the external data processing device. Stored configuration data specifies a communication protocol used by the control device from a first group of communication protocols and a communication protocol used by the external data processing device from a second group. The control interface unit uses any protocol from the first group of communication protocols for data transmission and selects the communication protocol used by the control device for data transmission with the control device. The communications unit uses any protocol from a second group of communication protocols for data transmission and selects the communication protocol used by the external data processing device for data transmission with the data processing device.Type: GrantFiled: February 14, 2018Date of Patent: December 21, 2021Assignee: DECKEL MAHO PFRONTEN GMBHInventors: Rolf Kettemer, Alexander Holzner, Gerhard Rausch

Patent number: 7278222Abstract: A method for measuring a program-controlled machine tool using a measuring sphere. According to this method the measuring sphere having known dimensions is positioned on a machine part. A sensing element installed in the machine is moved to a selected initial position in which it is located approximately 10 mm above the vertex section of the sphere. Then the sensing element is repeatedly moved until it contacts various points on the surface of the sphere, and the coordinate values of those points of contact are input into the controller. Thereafter the spatial position of the center of the sphere is calculated and compared with target values stored in the controller.Type: GrantFiled: February 16, 2006Date of Patent: October 9, 2007Assignee: Deckel Maho Pfronten GmbHInventors: Marzell Maier, Rolf Kettemer
