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.

A method of scanning an object using an analogue probe mounted on a machine tool, so as to collect scanned measurement data along a nominal measurement line on the surface of the object, the analogue probe having a preferred measurement range. The method includes controlling the analogue probe and/or object to perform a scanning operation in accordance with a course of relative motion, the course of relative motion being configured such that, based on assumed properties of the surface of the object, the analogue probe will be caused to obtain data within its preferred measuring range, as well as cause the analogue probe to go outside its preferred measuring range, along the nominal measurement line on the surface of the object.

A method for controlling a power tool includes ascertaining a workpiece characteristic of the workpiece to be processed from previously acquired measured values, determining the workpiece material from the workpiece characteristic of the workpiece to be processed, specifying initial values, which are suitable for processing the workpiece made of the determined workpiece material using the power tool, for machine parameters such as feed, speed, and torque, storing the initial values for putting the power tool into operation with machine parameters set to the initial values and/or putting the power tool into operation with machine parameters set to the initial values. A cooling constant is ascertained according to the Newtonian cooling law as the workpiece characteristic of the workpiece to be processed. To ascertain the cooling constant, the ambient temperature is measured, the workpiece is heated, and the actual temperature of the workpiece is measured, whereupon the cooling constant is computed.

A system includes a robot, a measuring device, and a processor. The robot is configured to dispense, based on at least one process parameter, a liquid adhesive bead onto a substrate. The measuring device is configured to measure at least one characteristic of the bead shape. The processor is configured to determine, based on a reference bead shape and at least one reference process parameter, response surface profile of the liquid adhesive. The processor is configured to compare the measured bead shape to a reference bead shape and, responsive to determining the measured bead shape is different than the reference bead shape, determine, based on the response surface profile, at least one updated process parameter. The updated process parameter is configured to cause the robot to dispense a second bead having the reference bead shape.

A method includes dispensing, by a robot within a manufacturing environment using at least one process parameter, one or more linear beads of a liquid adhesive representative of a target complex dispense path onto a surface of a substrate, the linear beads extending along a longitudinal axis and having a bead shape transverse to the longitudinal axis based on the at least one process parameter; and measuring, via a one-dimensional scan by a measuring device positioned within the manufacturing environment, at a plurality of discrete positions along the longitudinal axis of the linear beads, at least one characteristic of the bead shape.

A touch trigger probe interface for a machine tool is described that includes a probe communication portion for receiving probe event information from a touch trigger probe. A machine tool communication portion is also provided for outputting probe event information to a numerical controller of the machine tool. The machine tool communication portion outputs the probe event information as digital data packets, for example over a digital data bus. The digital data packets may include a time stamp and/or the touch trigger probe interface may receive timing information from the machine tool. A touch trigger probing system and a machine tool system including the probe interface are also described.

A servomotor control device includes: a servomotor; a driven body that is driven by way of the servomotor; a connection mechanism that connects the servomotor and the driven body to transmit power of the servomotor to the driven body; and a motor control unit that controls the servomotor, in which the motor control unit includes: a force acquisition section that acquires a drive force acting on the driven body at a connection part between the connection mechanism and the driven body; and a rigidity estimation section that estimates a magnitude of rigidity of the connection mechanism, based on position information of the servomotor and a drive force acquired by the force acquisition section when causing the servomotor to rotate in a state mechanically fixing the driven body.

Methods, systems, and non-transitory computer-readable storage media having programs are described for monitoring an ultrasonic bonding operation via acoustic and/or vibration measurements and analyzing the measurements in order to predict and/or characterize the quality of a weld resulting from the bonding operation. The measurements are non-destructively acquired and the characterization is expressed as a bond quality index value.

A method is described for measuring an object using a machine tool and a scanning probe. The scanning probe is driven along a scan path relative to the object whilst the scanning probe acquires probe data describing a series of positions on the surface of the object relative to the scanning probe. The scan path includes at least a first scan path segment for producing probe data that can be analysed to measure the object. The scan path is also arranged to impart a plurality of identifiable probe motions to the scanning probe that can be identified from the acquired probe data alone. Each identifiable probe motion is used to define a time stamp. This allows the probe data to be tied to commanded or nominal positions around the scan path.
