In accordance with some aspects of the present disclosure, a method producing a composite board comprising plastic and cellulose is described. The method includes transmitting a first signal to a pair of opposing hot-platens, receipt of the first signal causing the pair of opposing hot-platens to compress and heat a composite mat; transmitting a second signal to the pair of opposing hot-platens, receipt of the second signal causing the pair of opposing hot-platens to heat and compress the composite mat at substantially a first pressure for a first time period; transmitting a third signal to the pair of opposing hot-platens, receipt of the third signal causing the pair of opposing hot-platens to release the composite mat from the first pressure; and transmitting a fourth signal to a pair of opposing cold-platens, receipt of the fourth signal causing the pair of opposing cold-platens to compress and cool the composite mat.

A method for operating a fine blanking system comprises at least one fine blanking press having a first press unit, a second press unit, and one or more sensors. The method comprises obtaining parameter data from the one or more sensors for at least one of the first press unit, the second press unit, and another component of the fine blanking system during a first fine blanking process step. Adjustments are determined for control parameters of at least one of the first press unit, the second press unit, and the other component based on the parameter data. The adjustments are applied to the control parameters in a second fine blanking process step subsequent to the first fine blanking process step.

A press load measuring apparatus for a press machine of 1-point type includes: a plurality of strain gauges attached to the respective columns of the press machine, the plurality of strain gauges detecting respective strains generated in the respective columns in association with a press load acting on the slide; a bending moment calculator configured to calculate bending moments acting on respective columns based on an angle formed between a direction of movement of the slide and the connecting rod; and a press partial load calculator configured to calculate press partial load signals corresponding to the respective columns, an impact of bending strain components caused by the bending moments included in the strain signals being eliminated from the press partial load signals based on the bending moments acting on the respective columns detected by strain gauges attached to the respective columns.

A first process acquires drive system data indicating a dynamic state of a drive system. A second process performs frequency analysis on the drive system data so as to acquire analysis data indicating a power spectrum of the drive system data. A third process derives the Gaussian distribution of the analysis data and acquires a feature amount indicating the Gaussian distribution. A fourth process determines whether the drive system is operating abnormally based on the feature amount.

A load detection device includes a detector, a wireless transmitter, a power source, and a controller. The load detection device is provided in dies that includes a first die and a second die. The load detection device is installed on at least one of the first die and the second die and configured to detect whether the first die and the second die are in a closed state. The controller is configured to execute an electricity cutoff process of stopping electricity supply from the power source to the detector and the wireless transmitter when the closed state of the first die and the second die has continued for a predetermined time.

Press-fitting work is evaluated by appropriately determining a load when sliding occurs. A load-drop determination unit determines whether or not a load value detected by a load detecting unit exceeds a load-drop determination value decided based on a moving average value and a dispersion average value stored in a storage unit. A data substitution unit substitutes the load value which is determined to exceed the load-drop determination value in the load-drop determination unit with a predetermined value.

The present invention reduces the probability of malfunction occurrence when performing predictive control of a device being controlled. In this control device of one aspect of the present invention, a prediction model for a control variable is used to calculate a prediction value from a measured value of the control variable, and a desired command value of the control variable is determined by correcting a desired basic value in accordance with the calculated prediction value. The degree of correction is determined on the basis of weight. The control device controls the operation of the device being controlled according to the determined desired command value. The control device assesses whether the device being controlled is operated appropriately on the basis of monitoring data relating to the operation result of the device being controlled, and optimizes the weight of the correction to make appropriate control possible based on the assessment result.

Disclosed herein is a press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors configured to provide a first output signal indicative of deformation of the first sensing part. The method can be configured for determining if an error criterion based on the first output signal from the first displacement sensor has been met, and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.
