A diagnostic apparatus (10) diagnoses the existence of an abnormality in a tool for processing of a processing target by each of multiple working machines. The diagnostic apparatus (10) includes an acquirer (110) and a diagnoser (160). The acquirer (110) acquires program identification information identifying a program executed in each of the working machines, tool information indicating a type of the tool applied to processing, and transition information indicating transition of load in the working machine from the start to the end of the processing executed by execution of the program, at execution of the processing in the working machine. The diagnoser (160) diagnoses whether an index value of the load obtained from the transition information is out of a predetermined range corresponding to a combination of the program identification information, the tool information, and machine information identifying the working machine that transmits the transition information.

A three-dimensional shaping apparatus includes a plasticizing section that includes a drive motor, a heater, and a screw rotated by the drive motor and that plasticizes a material to form a shaping material, an ejection section that ejects the shaping material toward a stage, a moving mechanism section that changes a relative position of the ejection section to the stage, a prediction section that predicts a residual service life of the heater from an observation result of a state observation section that observes a state of the heater, and a control unit that controls the plasticizing section and the moving mechanism section to shape a three-dimensional shaped article. The control unit has a first mode in which a temperature of the heater is set to a first temperature and a second mode in which the temperature of the heater is set to a temperature lower than the first temperature, and shapes the three-dimensional shaped article in the first mode when a first residual service life when the temperature of the heater is set to the first temperature exceeds a first value, and shapes the three-dimensional shaped article in the second mode when the first residual service life is equal to or less than the first value.

A control system for evaluating residual operating life of a machine component of a machine tool includes a sensor and a control system. The sensor is disposed on the machine tool and is configured to sense movement of the machine component. The control device is configured to calculate a length of time based on a sense signal received from the sensor and sampled at a time point right after the machine component is freshly oiled, and to enable output of an alarm when determining that the length of time thus calculated is smaller than a predetermined length.

A numerical controller that collects data from an industrial machine and writes data into a storage medium includes: an interval setting unit that sets a time interval between cycles in which one cycle involves collection of operation information indicating an operating state of the industrial machine and writing of the collected operation information to the storage medium; a reduced service life calculation unit that calculates a service life of the number of writes of the storage medium reduced by the writing on the basis of the set time interval as a reduced service life; a determining unit that determines whether the calculated reduced service life exceeds a prescribed threshold; and a signal output unit that outputs a signal indicating that the reduced service life exceeds the prescribed threshold when it is determined that the reduced service life exceeds the prescribed threshold.

A dental machining system for manufacturing a dental restoration including: a dental tool machine (1) which has: a dental blank holder for holding at least one dental blank (2) relatively movably with respect to one or more dental tools (3); one or more driving units (4) each for movably holding at least one dental tool (3) for machining the dental blank (2), a control unit for controlling the dental blank holder and the driving units (4) based at least on a temporal trajectory of the dental tool (3) relative to the dental blank (2) and a spatial amount of material removal from the dental blank (2) along the temporal trajectory. The control unit executes a trained artificial intelligence algorithm.

An assistance method for execution of a format change in an automatic machine can include dividing the format change into an orderly succession of operations for the removal of components designed for the old format and installation of components designed for the new format; communicating the orderly succession of removal and installation operations to an operator; electronically and automatically detecting the actual presence or absence of a component designed for the old or new format before communicating to the operator the operation for removal or installation of the component; electronically and automatically detecting the actual absence or presence of a component designed for the old or new format after having communicated to the operator; and communicating to the operator the operation following an operation for the removal or installation of a component only after having electronically and automatically checked for the actual absence or presence of the component.
