摘要： A method is suggested for welding workpieces, particularly coated workpieces, and a device is suggested for implementing the method. By means of the device, at least at the welding point, alternately a zero gap and an outgassing gap adjustable in its height for the escape of the gases and vapors occurring during the welding operation can be generated, for this purpose at least a first workpiece being moved relative to a second workpiece. The method is characterized in that the relative movement between the workpieces is force-controlled and/or path-controlled.

摘要： A probe head having a probe head base and a stylus is provided for contacting a surface point on a workpiece. The stylus is moveable relative to the probe head base and has a defined rest position relative to the probe head base. For the contacting, the probe head is moved relative to the workpiece until the stylus touches the surface point with a defined contacting force.

摘要： A method for correcting errors in a coordinate measuring machine having a measuring head which is adapted to move in at least two different spatial directions. Measuring scales and measuring lines are assigned to each spatial direction. The measuring lines of different spatial directions intersect, and correction values are determined along the measuring lines at predetermined values of the scales in order to correct for elastic and/or geometric errors of the scales and/or of the guiding mechanism for moving the measuring head. According to one aspect of the invention, the correction values determined along a measuring line of a first spatial direction are modified such that the modified correction value of this measuring line assumes a predetermined value at the point of intersection with a first measuring line of a second spatial direction.

摘要： The invention is directed to a method for controlling a coordinate measuring apparatus wherein the probe head (2) and the probe pin (19) of the apparatus are control driven in accordance with desired data Pi. The probe pin (19) is movably attached to the probe head (2). In the method, the probe pin for measuring the workpiece (15) can touch down on the surface of the workpiece to be measured or can be lifted off of this surface. The speed of measurement is increased by selecting the angle (.alpha.down, .alpha.up) between the direction of movement vres of the probe head (2) when touching down or when lifting off and the projection of the direction of movement toward the plane tangential to the workpiece surface in the touchdown/liftoff point (Pdown, Pup) to be less than 30.degree..
