ABSTRACT:
A component (22; 23; 122) is positioned on or formed as part of a plate (20) which is supported by a bearing (14) and which is supported at the position of the component (22; 23; 122) to be positioned by a support (8). The positioning is carried out by a die (10) which together with the support is controlled by a control system, comprising one or more reference signal sources, comparators (24, 30) and amplifiers (25, 31) , in such a way that the component (22; 23; 122) is accurately positioned relative to reference plane (26) relative to the plate. When the desired position of the component is reached, it is ensured that no elastic deformation are present in the plate. For this purpose, a device for carrying out the method comprises a control system (29, 30, 31, 32; 8, 36, 38; 138, 148) which controls the die (10) and/or the support (8) positions or support the die and the support or the plate (20) in such a way that the plate is free from undesired elastic deformations at least when the component reaches the desired position.
