    Abstract: In a method for operating a machine tool and a corresponding machine tool system, a generic first data model and engineering data are provided in an external server device. The engineering data contain information relating to a machine tool. After a user query regarding an operation of the machine tool, the first data model is translated and/or modified to become a second data model. This occurs in accordance with the engineering data and technical data of the user query by the external server device. The second data model is transferred from the external server device to the machine tool, and a control unit of the machine tool can operate the machine tool according to the second data model.

  • Patent number: 11127204
    Abstract: An improved part optimization process in additive manufacturing is provided, which uses a finite element analysis only where boundary parameter differentiation is detected. For a given part being manufactured, such as in DMLS, thermal effects of adjacent volumes with no boundary parameter differentiation are ignored in the part optimization process. For example, if a given volume is over a volume of the same material, no computational analysis is conducted, but if a volume of metal is over air, then the computational analysis is conducted. This results in significantly less computational time being required. Further, the present invention uses computation equipment remote from the DMLS part production equipments, connected instead via the internet or other such “cloud computing” arrangements.

    Abstract: A numerical controller (100) capable of shortening the cycle time during tool replacement without modifying an existing program is provided. A numerical controller (100) includes a block information checking unit (108) that analyzes a program for respective blocks. When it is determined that one or two or more feed axis positioning commands are present before a tool replacement command found in the analysis result of the program, the block information checking unit (108) modifies the analysis result of the program so that a rotating tool axis orientation operation in the tool replacement command is executed during execution of a feed axis positioning command in any one of the one or two or more feed axis positioning command blocks.

  • Patent number: 10628618
    Abstract: A drill bit (10), for example of a fixed cutter type, comprises at least one structure, for example a blade, having first and second rows of cutters (35a-h) thereon. The first row is configured to achieve suitable performance when the drill bit drills in concentric mode. The second row of cutters is configured to improve the performance of the first row of cutters when the drill bit drills in eccentric mode. For example, the second row increases depth of cut and wear resistance in eccentric mode drilling. The drill bit may be mounted on a bent motor (120) used in directional drilling.

  • Patent number: 10564625
    Abstract: Improvements in a high speed smooth tool path is presented where the high speed smooth tool path to be used for primarily finishing for finishing any type of walls (negative/positive drafted) for any given bounded region be it 3, 4, 5, . . . n sided shape. The tool path incorporates a combined strategy for finishing the walls while removing any excess material leftover from a previous larger diameter cutter. This tool-motion can be utilized for roughing the regions by approximating the walls by offsetting the regions inwards. The finished boundaries are offset inwards and then cut using these methods. This is optimized as opposed to moving the cutter at a consistent speed in the cutting path. This is performed to eliminate the wasted tool-motion to the maximum extent. This technique is implemented for roughing any closed or open bounded areas regardless of the walls being straight, drafted (negative/positive or both).

  • Patent number: 10552511
    Abstract: The technique relates to a system and method for data-driven anomaly detection. This technique involves identifying region of interest from the data based on dimensionality reduction technique and change point detection algorithm. A reference data can be obtained separately or can be obtained from the test data also, wherein the reference data represent the normal operating condition of a system. The reference data are classified into different groups representing different modes of operation of the system. A control limit is determined for the different groups. The data within the region of interest are mapped with the different groups of the reference data and it is determined if the mapped data fall outside of the control limit of the mapped group. Finally, at least one abnormal event is detected by applying a heuristic algorithm on the data within the region of interest which are outside the control limit.

  • Patent number: 10533920
    Abstract: Automatic fault diagnosis is performed on vibration data sensed from a machine. A set of faults to screen for is identified from the machine configuration. For each fault there are characteristic symptoms. For each characteristic symptom, there is a corresponding indication used to diagnose the symptom. The indications are based on analyses of the current vibration data. The diagnosed symptoms have weights assigned according to a Bayesian network, and are used to derive a Bayesian probability for the fault. A fault having a Bayesian probability exceeding a threshold value is identified as being present in the machine. For each fault a confidence level is derived. The confidence level for a first fault is based on a similarity between characteristic symptoms for the first fault and characteristic symptoms for each one of the other faults being screened.
