  • Patent number: 10474131
    Abstract: A numerical controller includes a data table on which data in which a size of a machining area and a setting value of a parameter, which is influenced by a size of a machining area, are associated with each other is registered. Further, the numerical controller estimates a size of a machining area based on a setting value of a parameter used for control of a machine tool. In the case where data corresponding to the estimated size of the machining area is registered on the data table, the numerical controller acquires a parameter setting value corresponding to the size of the machining area from the data table so as to set the parameter setting value.

  • Patent number: 7643966
    Abstract: A computer model of a physical structure (or object) can be generated using context-based hypothesis testing. For a set of point data, a user selects a context specifying a geometric category corresponding to the structure shape. The user specifies at least one seed point from the set that lies on a surface of the structure of interest. Using the context and point data, the system loads points in a region near the seed point(s), and determines the dimensions and orientation of an initial surface component in the context that corresponds to those points. If the selected component is supported by the points, that component can be added to a computer model of the surface. The system can repeatedly find points near a possible extension of the surface model, using the context and current surface component(s) to generate hypotheses for extending the surface model to these points.

  • Patent number: 6597966
    Abstract: Every time the cumulative number of revolutions of a spindle rotating motor reaches a cumulative number of revolutions set in a data table, a CPU reads out, from a data memory section, moving positions of a workpiece and tool at the reached cumulative number of revolutions and the next cumulative number of revolutions, and a spindle rotational speed instruction value at the reached cumulative number of revolutions. The CPU sets the reached cumulative number of revolutions as a start point and the next cumulative number of revolutions as an end point, and divides the interval between the start and end points at predetermined timings. The CPU determines moving positions of the workpiece and tool at divided timings on the basis of the readout moving positions of the workpiece and tool. The CPU outputs the spindle rotational speed instruction value as a spindle rotational speed instruction signal to a reference spindle rotational speed setting circuit to control the rotational speed of the spindle rotating motor.

  • Patent number: 6377864
    Abstract: The present invention relates to a system and method therefor of sorting and unloading various pieces cut from sheet blanks which have different dimensions in a sheet metal fabricating environment. To achieve this end, prior to the production run, the various program routines whose operations for effecting the cutting of the sheet blanks are retrieved and the data relevant to the to be cut pieces are grouped and analyzed so that pieces of different dimensions cut in accordance with the different program routines are respectively allocated to the corresponding sorting addresses for unloading. Accordingly, different pieces with the same dimension cut from different program routines during the same production run are unloaded to the same location of the unloader area. Optimization of the unloading process and optimal utilization of the available loading space are thereby achieved.
