  • 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.

The program is executed, and the execution time of each of the blocks of the program and the execution time of the entire program are measured. Then, a predicted time until an in-position state is established is loaded. The execution time of the entire specified program is loaded. The execution time of each bock and a moving speed for each block are calculated, then a speed for each block is substituted with the calculated moving speed.

  • Patent number: 9760079
    Abstract: In a wire electric discharge machine that machines a blade section of a cutting tool, in a state in which a rod-shaped reference jig is fixed to a rotary axis, a position on an outer circumferential surface of the reference jig is measured at each rotation position and stored. A rotational run-out error is calculated based on the stored rotational run-out position information, and a machining program is corrected to cancel the rotational run-out error.

  • Patent number: 9715225
    Abstract: Positions to be synchronized with a reference value are stored as command data in table format. Velocity changing points of a tool path designated by the table format data are calculated. Two intersection points between the tool path and a circle or a sphere having a designated radius and centered on the velocity changing point are connected by a smooth curved tool path according to a multidimensional function or the like. In this way, the table format data is corrected.

  • Patent number: 9636238
    Abstract: Systems, methods, and software are provided for assessing manufacturing errors of a prosthetic socket to facilitate a clinical assessment of the socket. The embodiments disclosed herein may align and compare a manufactured socket shape to a desired socket shape to determine whether clinically significant errors are present in the manufactured socket. A mean radial error (MRE) may be calculated and compared to a set threshold. If the MRE falls below the threshold an interquartile range (IQR) may be calculated and compared to an IQR threshold. If the IQR falls below the IQR threshold, surface normal angle errors (SNAE) may be calculated and plotted to the surface model. If the SNAE plot does not include closed contour regions, the socket may proceed to patient fitting. If the MRE or IQR thresholds are exceeded, or if the SNAE plot indicates closed contour regions, the socket may be reshaped accordingly, prior to fitting.

  • Patent number: 9606528
    Abstract: In a numerical controller for controlling acceleration and deceleration on the basis of a stopping distance, a stopping distance calculation module calculates an acceleration for stopping a drive axis with a probe on the basis of a distance that the drive axis with the probe moves from a current velocity to a stopped state when stopping at a maximum acceleration at which a machine tool does not receive shock, and on the basis of a stopping distance at which the probe is not be damaged. An acceleration and deceleration control module calculates a velocity of the drive axis for each of interpolation periods on the basis of the acceleration calculated by the stopping distance calculation module. An interpolating module outputs data that controls the drive axis, on the basis of the interpolation data and the velocity of the drive axis calculated by the acceleration and deceleration control module.

  • Patent number: 9479903
    Abstract: A network node in a mobile network monitors vehicle speed based on the registered User Equipments (UEs)/Vehicles. The network node receives information of the moving UE/Vehicle from other network nodes in the mobile network, and determines the corresponding UE/Vehicle moving speed information based on the collected information. For each UE/Vehicle, the network node creates a speed information record indicating the UE/Vehicle moving speed information. The network node then transmits the speed information record to other messaging nodes in order to (i) send warning message to the moving UE/Vehicle when the speed is about to exceed or has exceeded the speed limit, and (ii) to deliver the speed information record to the responsible/ticketing authorities/entities when the moving UE/Vehicle has violated the speed limitation in a certain area.

  • Patent number: 9383742
    Abstract: A system and method for error compensation in positioning a complex-shaped gas turbine engine part during manufacturing thereof with a machine. Theoretical measurements for a plurality of control points on the part are first retrieved. Actual measurements for the control points are then acquired in a coordinate system of the machine. If an error between the actual and theoretical measurements is beyond a tolerance, a transformation matrix is computed. The transformation matrix represents a transformation to be applied to the coordinate system to adjust a pose thereof for compensating the error. The transformation matrix may be computed and applied to the coordinate system iteratively until the actual measurements are brought within tolerance. A machining program may then be generated for manufacturing the part accordingly.
