摘要： A method of measuring workpieces on a machine tool is described. An analogue or scanning probe is moved along a pre-defined path relative to the workpiece, the predefined path comprising nominal positions of the probe relative to the workpiece. Measurements are taken with the analogue or scanning probe during movement. These output measurements represent the position of the workpiece surface relative to the probe. The difference between measurement output of the probe at a position of the probe and target or nominal probe output at this position represents the error of the workpiece.

摘要： On a machine tool, a program (12) receives data from a scanning or analogue probe P, measuring a feature of a workpiece W. This data is combined with assumed machine position data during the scanning movement. This avoids having to break into the servo feedback loop (24) to get actual measured machine position data. The assumed machine position data can be derived from a part program (20) which controls the scanning movement. Several ways are described for compensating for errors between the assumed machine position values and the actual values.

摘要： The invention relates to a method for mounting an add-on part (3) on a production part (1), particularly on a vehicle body during which the add-on part (3) should be aligned in a positionally precise manner with regard to a reference area (12, 13) on the workpiece (1). To this end, a robot-guided mounting tool (5) is used that is connected to a sensor system (20) in a fixed manner. In order to achieve a positionally precise alignment of the add-on part (3), an iterative control method is run through, over the course of which an (actual) measured value of the sensor system (20) is firstly generated that is compared with a (set) measured value generated within the scope of a setting-up phase. A displacement vector of the mounting tool (5) is calculated based on the difference between the (actual) measured value and the (set) measured value while using a Jacobian matrix that is calculated within the scope of the setting-up phase, and the mounting tool (5), along with the add-on part (3) fixed therein, is iteratively displaced by these displacement vectors relative to the production part (1) until the desired position is attained. A metric calibration of the sensor system (20) can be forgone in order to perform this positioning task.

摘要： The invention relates to a method for the automated mounting of several add-on parts (3, 3') on a production part (1), particularly on a vehicle body, during which the add-on parts (3, 3') should be fastened to the workpiece (1) whereby being aligned in a positionally precise manner with regard to one another. Each add-on part (3, 3') is held in a mounting tool (5, 5') that is guided by a robot (7, 7'). A sensor system (18, 18'), which is connected in a fixed manner to the mounting tool (5, 5') and which is provided with at least one sensor (19, 19'), is fastened to at least one of the mounting tools (5, 5'). An iterative control process (A-2') is used for displacing the mounting tools (5, 5') with the aid of measured values of the sensors (19, 19') into an anticipation position (23,23') in which the add-on parts (3, 3') that are held inside the mounting tools (5, 5') are aligned in a positionally precise manner with regard to one another. Afterwards, the mounting tools (5, 5'), together with the add-on parts (3, 3'), which are held therein and which are aligned in a positionally precise manner with regard to one another, are guided relative to the production part (1) from the anticipation position (23,23') and into a mounting position (27, 27') in which they are joined to the production part (1).

摘要： Large machines, especially those having working envelopes in excess of fifteen feet, exhibit unacceptable errors because of thermal expansion and mechanical misalignments between the axes. The errors have traditionally been minimized by enclosing the machine in a thermal enclosure, by careful calibration, or by mounting a laser interferometer on each axis. These solutions are costly, may require frequent recalibration, and do not correct for small rotations of one axis relative to another axis due to wear etc. The present invention uses an interferometric laser tracker or a comparable 3D position sensor to measure the position of a retroflector attached to the end effector, e.g. a machine head when the machine comes to rest. A computer compares the measured position to the desired position according to the machine media, and adds the appropriate correction with trickle feed media statements to move the machine to the correct position prior to further machining.

摘要： A laser work station has a base member, a laser head (18) mounted on a laser head support carried on the base member for movement of the laser head relative to the base member, so that it is movable thereon in X, Y and Z axes. A guidance system effects precision movement of the laser head in the X, Y and Z axes to move the beam about a workpiece. The workstation also includes an optical sensor assembly (120) comprising a light source (182), and light sensor (184) about the light source (182) to detect light reflected from the surface of the workpiece (38). The sensor assembly (120) is operable to detect reference formulations on the workpiece (38) as it is moved thereabout. The computer control (28) indexes the sensor assembly (120) to a preselected position relative to the approximate position of a reference formation on the workpiece (38) and moves it in a predetermined path from the preselected position to sense passage of the beam over the edge of the reference formation, and the work station uses data obtained from such sensing of the passage of the beam over the edge of the reference formation to adjust the coordinates of the guidance system to reflect the actual position of the workpiece.

摘要： A motion program of a robot is easily changed using a work body, instead of using a master body. The motion program of the robot is corrected by correction data obtained by cameras (2, 3, 4). When a point (Q) of the motion program is to be changed to another point (Qn), a point (Qa) on a work body (22) is changed to a change point (Qan). In a robot control system, this change point is read out as respective coordinate values and converted into space coordinate values. Further, these space coordinate values are acted on by inverse correction data to be converted into reference space coordinate values on masterbody (21). These reference coordinate values are inversely converted into reference coordinate values of respective axes. Since the motion program is instructed by the reference coordinate values of the respective axes, the point (Q) of the motion program is changed to the other point (Qn) by use of the reference coordinate values of the respective axes. By this operation, the motion program can be easily changed without using the master body (21).
摘要翻译：使用工作体容易地改变机器人的运动程序，而不是使用主体。通过由摄像机（2,3,4）获得的校正数据校正机器人的运动程序。当将运动程序的点（Q）改变为另一点（Qn）时，工件（22）上的点（Qa）改变为变化点（Qan）。在机器人控制系统中，将该变化点作为相应的坐标值读出并转换为空间坐标值。此外，这些空间坐标值通过逆校正数据进行操作，以转换为主体（21）上的参考空间坐标值。这些基准坐标值被逆转换成各轴的基准坐标值。由于通过各轴的参考坐标值指示运动程序，运动程序的点（Q）通过使用各轴的参考坐标值而改变为另一点（Qn）。通过该操作，可以容易地改变运动程序而不使用主体（21）。

摘要： Une pièce est portée par un dispositif support de pièces (40; 40'; 40''; 44'; 142; 144) de façon qu'elle soit déplacée dans un premier sens grâce à la coopération entre le dispositif de serrage et le dispositif d'avance de pièces (46; 142; 144), ces deux dispositifs étant supportés par un chariot (16) effectuant un déplacement dans un deuxième sens perpendiculaire au premier sens de déplacement afin de déplacer une pièce par rapport à une tête de machine à coudre. Les deux dispositifs sont montés des deux côtés d'une ouverture longitudinale (42) s'étendant dans le deuxième sens de déplacement, dans l'alignement du point de pénétration de laiguille (N). Des moteurs pas-à-pas (24; 60) servent à mouvoir le chariot et à actionner les dispositifs de serrage et d'avance de pièces (46; 142; 144) sous commande programmée. Une caméra (70) se trouvant dans l'axe de l'ouverture (42) permet d'analyser les contours de la pièce avançant en-dessous. Un ordinateur détermine, en fonction des contours de la pièce analysés, le type de pièce dont il s'agit, ainsi que son orientation et son emplacement sur le dispositif de support de pièces, sollicite un fichier approprié de modèles de points et modifie les données en fonction de l'orientation et de l'emplacement de la pièce. Celle-ci est ensuite cousue conformément aux données ainsi modifiées.
