A numerical value control device, a numerical value control system, a control method, and a recording medium, with which a primary shaft can be retracted to an appropriate position when executing magazine rotation correction. In a state in which a primary shaft is stopped at a point M4 on a tool exchange path 52, a CPU determines whether there is a rotation deviation in the magazine in order to restore the position of the primary shaft in a machining region. If it is determined that there is a rotation deviation, the CPU detects a Z axis of the primary shaft, and determines whether the detected position of the Z axis is at a Z axis ATC origin point. If the detected position is not at the Z axis ATC origin point, there is a possibility that the primary shaft is positioned within a magazine rotation region.

A machining device includes: a positional deviation detection unit configured to calculate a correction value for correcting a positional deviation between an ideal contour line and an actual contour line in each of a plurality of angular directions based on a center of a hemispherical shape of a tool; a distance effect coefficient calculation unit configured to calculate a first distance effect coefficient indicating a degree of influence of the positional deviation when machining a second machining point, according to a distance between the tool and the second machining point in a case where a machining point machined by the tool transitions from one-point machining including a first machining point in the workpiece to two-point machining including the first machining point and the second machining point; and a positional deviation correction unit configured to correct the positional deviation of the tool.

Provided are a wire electric discharge machine, a correction device, and a correction method which accurately correct position information indicating the position of a supporting point of each of an upper guide and a lower guide. The correction device includes: a storage unit that stores the position information; an inclination control unit that causes a wire electrode to incline at a predetermined angle; a measurement unit that measures a relative movement amount from a state in which the lower guide and a measurement site are separated by a predetermined distance in a relative movement direction to a state in which the wire electrode inclined at the predetermined angle reaches the measurement site; and an information correction unit that corrects the position information of the storage unit on the basis of the predetermined angle and the relative movement amount.

The present invention corrects errors made by a machining tool having a discretionary machine configuration, by using a graph in which constituent elements serve as nodes. This control device comprises: a control point coordinate system insertion unit that inserts, as nodes, a control point and a coordinate system, for each node of a machine configuration graph; an identifier allocation unit that allocates an identifier to the inserted control points and coordinate systems; an error information storage unit that stores information relating to a machine error on a control subject, and the identifier allocated to the coordinate system in which the machine error was observed; an error node generation unit that converts the machine error to an equivalent error node; and an error node addition unit that adds the error node to the machine configuration graph.

A calibration system includes: a calibration device; an operating computer configured to acquire monitoring data generated from calibration target equipment and to determine whether or not to perform calibration on the target equipment based on the monitoring data; and a transport device configured to transport the calibration device and to mount the calibration device on the target equipment when it is determined that calibration is to be performed on the target equipment. The calibration device is configured to collect calibration data from the target equipment and to transmit the calibration data to the operating computer after the calibration device is mounted on the target equipment, and the operating computer is configured to calculate a correction factor for the monitoring data based on the calibration data.
