The invention relates to a device (15) and a method (V) for machining a tool (16) by removing material. The tool is first of all measured in three dimensions using a measuring unit (17) and a three-dimensional virtual tool model (M) is produced therefrom. This virtual tool model (M) is compared with a reference contour (R) from a particular tool data record (WD). If a match was determined, a machining program (PR) assigned to the tool data record (WD) is selected and a desired contour (SK) is determined by fitting the reference contour (R) into the three-dimensional virtual tool model (M). The tool (16) can then be machined on the basis of this desired contour (SK).

The present invention enables the simple determination of the cause of an abnormality of a machined surface of a machined workpiece regardless of the proficiency of a user.

The present invention comprises: a machining shape model storage unit that stores at least a first, second, and third machining shape model which are generated on the basis of three machining position data items of at least three steps in series of machining an object with a machine tool; a machining shape model selection unit that selects the first and second machining shape models, and the second and third machining shape models; a machining shape model acquisition unit that acquires the first and second machining shape models and also acquires the second and third machining shape models; and a difference calculation unit that finds a set of the distances between the machined surface of the first machining shape model and the machined surface of the second machining shape model as a first difference set, and finds a set of the distances between the machined surface of the second machining shape model and the machining surface of the third machining shape model as a second difference set.

A numerical controller includes: a control unit that interprets a machining program including tool information for identifying a tool to control the axis of a machine tool; a feedback information acquisition unit that acquires, from the machine tool, feedback information indicating the position of the axis; a tool change information acquisition unit that acquires, from the machine tool, change information indicating that the tool has been changed; a synthesis information generation unit that synthesizes the feedback information with the tool information and change information acquired by the tool change information acquisition unit; a shape information storage unit that stores shape information indicating the shape of the tool; a machining simulation unit that executes workpiece machining simulation on the basis of the synthesis information and the shape information; and an output unit that outputs machined shape information indicating the shape of the machined workpiece.

A numerical controller controls a machine tool which carries out machining by moving a workpiece or a tool using a periodic operation cycle for repeatedly executing the same operation. The numerical controller stores command data of each execution period of a superposition cycle superimposed with the periodic operation cycle. Command data sets of the superposition cycle are synthesized every execution cycle in synchronization with execution timing of the periodic operation cycle.

An electric tool system includes an electric tool and an inspection device. The electric tool includes: a tightening unit configured to tighten a workpiece onto an attaching target by driving force of a drive source; and a sensor configured to measure a tightening torque provided by the tightening unit. The inspection device includes a measuring unit configured to measure tightening force applied from the tightening unit. The electric tool system further includes an association processor configured to associate a first torque measured value with a second torque measured value. The first torque measured value corresponds to a measurement result by the sensor. The second torque measured value corresponds to a measurement result by the measuring unit.

The industrial power tool system includes a controller physically disposed in a predefined location within an assembly line work station. The controller has a first radio frequency transceiver that propagates a digital communication signal at a predefined power. A human operable portable power tool has a second radio frequency transceiver configured to communicate with the first transceiver, providing a signal strength datum indicative of the received signal strength. A processor circuit causes the tool to perform a sequence of predefined assembly job steps that are mediated by the processor circuit according to a control loop running on the processor circuit. The processor circuit compares the signal strength datum to a predefined signal strength threshold to determine if the distance between the first and second radio frequency transceivers is less than a predefined distance that defines a home area proximate the controller. The processor circuit uses the test of this distance as at least one operative step in the control loop that mediates the sequence of predefined assembly job steps.
