| Zusammenfassung | We show how absolute length measurements by interferometry can be applied to measure the dimensional and thermal stability of joints. In order to investigate joining techniques, representative joints were fabricated by a number of methods including screwing and gluing. By using gauge blocks as joining parts parallelism and flatness were achieved which are needed for precision interferometric measurements. We were able to examine the dimensional behavior (i.e. change of length or orientation) of the sample joints on an accuracy level of about one nanometer. Stability has been investigated longitudinally and laterally to the connection interface, also mutual tilting of the parts was detected by analysis of the phase topographies. Measurement results of about one year show that screwed joints do not exhibit significant changes of length, orientation or response to temperature variation. This is different for adhesive joints where dimensional changes of up to 100 nm were observed. |
