The measurement of force and surface roughness influence on the size of the linear measurement accuracy of components with a highly flexible material using 3D surface fundamentals is studied in Doctoral thesis “Measurement Force and Surface Roughness Influence on Measurement Precision of Linear Dimensions of Components from Highly Elastic Materials”. There is also a well-founded 3D surface parameters and model selection elastic contact calculated in the case. During experimental measurements obtained principal theories and experiments coincidence. Selection methodology of a highly flexible material component and a suitable measuring instrument was developed as well. The thesis is written in Latvian and includes 92 pages, introduction, 7 chapters, conclusion, a list of information sources, 2 annexes, 18 tables and 35 pictures.
