A method for controlling a level of screwing quality of a screwdriver relative to a predetermined screwing objective. The method includes: obtaining, at a predetermined angular frequency, a series of doublets representative of a rise in screwing torque for at least one screw, constituting a first table of values, each doublet including an angle value and a torque value; determining, from the first table, a second table of values presenting the torque as a function of the angle and being representative of the true characteristic of the at least one screw; determining a third table of values, presenting the torque as a function of the angle and being representative of disturbances induced by the screwdriver during the rise in torque, from the first and second tables; analysis of the third table, delivering information representative of a dispersion and/or a deviation relative to the screwing objective, resulting from the screwdriver-induced disturbances.

An information processing device is connected to a measurement device provided in the vicinity of a machine tool for machining a workpiece using a tool and a numerical control device configured to control the machine tool. The information processing device includes: a display unit configured to display information; a first acquisition unit configured to acquire, from the measurement device, measurement information measured by the measurement device; a second acquisition unit configured to acquire, from the numerical control device, state information indicating a state of the machine tool; and a display control unit configured to cause the display unit to display the measurement information and the state information.

In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.

Components are assembled in an industrial machine together with a controller. The components each include a unique identification information memory portion and a component-side configuration history memory portion. The unique identification information memory portion stores, as unique identification information, identification information of the component itself, which is providable to the controller. The component-side configuration history memory portion stores configuration histories that each summarize, in terms of an acquisition timing from the controller, the unique identification information of the component itself, controller identification information of the controller that was used to configure the industrial machine together with the component itself, and unique identification information of other ones, than the controller, of the components, which were also used to configure the industrial machine together with the component itself.

An error compensation method includes outputting at least one of a plurality of calibration-master conditions including a type of a calibration master that includes targets, obtaining measurement values of positions of the targets by detecting the positions of the plurality of targets under the calibration-master condition using a sensor mounted to the main spindle, and calculating an error value using the measurement value and a calibration value of the position of the target. The error compensation method further includes approximating a relation between the measurement values and the error values by a curve and a straight line, calculating a compensation parameter of a positioning error of a translational axis based on an approximate curve in a partial range of a stroke of the translational axis, and calculating the compensation parameter of the positioning error based on an approximate straight line in another range of the stroke of the translational axis.

The present disclosure relates to an apparatus and a method for detecting an abnormality of a tool of a machine tool, and more particularly, to an apparatus and a method for correcting backlash of a machine tool, which are capable of repeatedly measuring a load of a workpiece transferring unit or a workpiece machining unit, and automatically detecting an abnormality of a tool based on a normal range of load data that are proportional to a standard deviation of the load data measured based on any one of a mode value, a mean value, or a median value of the repeatedly measured load data.
