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 detection device for detecting a workpiece with multiple surfaces includes a rotary table carrying the workpiece and moving the workpiece by rotation and a plurality of photographing devices arranged at a plurality of different positions around the rotary table. Each photographing device has an image capture device capturing an image of a corresponding surface of the workpiece that is moved to the image capture device. An orientation of the image capture device is defined by a first offset angle and a second offset angle when the image capture device captures the image of the corresponding surface of the workpiece.

In a method for automated positioning of a blank in a processing machine provided with a housing and a spindle unit with an electric motor, a control unit for control and electrical supply of the processing machine, a computer producing processing programs for manufacturing workpieces, a workpiece holder, and an image recording unit that optically records image data of a blank received in the workpiece holder, a blank is fixed in the processing machine and the image recording unit produces an image of the blank. A division of the blank into an already processed region and into an unprocessed region based on the image data of the image is performed. A workpiece geometry to be produced is assigned to the unprocessed region of the blank, and a milling operation is performed on the unprocessed region. In a variant of the method, the image recording unit is separate from the processing unit.

A positioning apparatus for positioning a tactile or optical roughness sensor, a probe or some other measuring instrument with respect to a workpiece can be secured to a movement device of a coordinate measuring machine. The positioning apparatus has a drive that produces a relative movement between two parts of the positioning apparatus, and an inhibiting device, which inhibits the relative movement between the two parts. For this purpose, the inhibiting device has a first friction element and a second friction element each having unlubricated friction surfaces. The friction surfaces are pressed against one another with a normal force that is not variable during the operation of the positioning apparatus. A coefficient of sliding friction that is less than 0.15 acts between the friction surfaces in the case of dryness and without lubrication. Typically, the inhibiting device is arranged in a flexspline of a strain wave gearing.

Provided is a three-dimensional measurement device applicable to a machining machine. A sensor head contains a body and a collet chuck. A light emitting window and a light receiving window are provided on the front end of the body. A non-contact sensor is incorporated in the body. Laser light emitted by the non-contact sensor is radiated onto a workpiece through the light emitting window. Laser light reflected from the surface of the workpiece is received by the light receiving window. A collet chuck is attached to the rear end of the body. The collet chuck has the same shape as a collet chuck provided by each tool housed in a tool magazine of a machining center.

Disclosed is a method for an all-laser hybrid additive manufacturing. After a matrix is obtained by means of selective laser melting forming, a subtractive forming is carried out on the matrix by means of a pulse laser to form a cavity, and the cavity is then packaged to obtain a forming material with an internal cavity structure. A laser precision packaging method is used in the method based on the melting of the laser selective region. Also disclosed is the apparatus, comprising a laser unit (2), a control unit (4) and a forming unit (6). The laser unit is in light path connection with the forming unit, and the control unit is electrically connected with the laser unit and the forming unit respectively. The laser unit comprises a first laser light source to and a second laser light source. The forming unit comprises a welding unit (68), and the welding unit is controlled by the control unit and is matched with the laser unit for the additive manufacturing.

The invention relates to achieve a rapid, reproducible and reliable characterization of the quality of ply-by-ply machining of multilayer materials. This method for inspecting ply-by-ply machining of a part (10) made of multilayer composite material under repair by machining a ply-by-ply staggered or continuously sloped cut out in a stack of plies of various successive orientations includes taking images (IA to ID), under lighting of different orientations (12), of a surface area (10a) of the machined part (10) to be inspected; performing an analysis by comparing the images (IA to ID) pixel by pixel (P0) in order to define the orientation of each pixel (P0) as corresponding to that of the image in which this pixel has a higher brightness; if the pixel has a similar brightness in all the images (IA ID), this pixel (Pr) is attributed to a resin; constructing a map (5) in units of ply of the surface area to be inspected (10a) by applying the preceding analysis to all of the pixels; estimating a machining quality level from the map (5) produced, and archiving (2m) each map (5) thus produced as a machining result.

Disclosed is a method and apparatus for determining a depth of a feature (4) formed in an object (2), the feature (4) having been formed in the object (2) by a cutting tool (38). The apparatus comprises: a camera (42) configured to capture an image of the feature (4) and a portion of the object (2) proximate to the feature (4); and one or more processors operatively coupled to the camera (42) and configured to: detect, in the image, an edge (72) of the feature (4) between the feature (4) and a surface of the object (2); using the detected edge (72), calculate a diameter for a circle (74, 76, 78); acquire a point angle of the cutting tool (38); and, using the calculated diameter and the acquired point angle, calculate a depth value for the feature (4).
