Out-of-plane ESPI ESPI (Electronic Speckle Pattern Interferometric) technique was developed for measuring the bulge deformation of the film material obtained from the bulge test. In this study, the bulge test was carried out using the copper film 18 ìm thick and with the bulge testing system including the ESPI system. It can be verified that the 3-dimensional profiles of the deformation measured for the rectangular and square windows were simulated with the cylindrical and spherical vessel models, respectively. From the test, pressure-deformation curve were obtained by consequently acquiring the speckle patterns of the bulged membrane. Furthermore, the stress-strain curve could be determined from the pressure-deformation curve and the elastic modulus for the copper film were determined.

The demand which detects the defect of a detailed structure is increasing. However the resolution of the general optical inspection method is not enough. In order to raise resolution, utilizing the advantage of optical detection, we proposed the novel optical inspection method. Although the steady value was conventionally set up as an initial value of processing, a design value is set as an initial value in this research. As a result, highly precise defective detection is attained rather than the conventional technique. Moreover, the possibility of the detection using low magnifying power is confirmed.

Never-ending growth of market`s demands causes necessity to control not only geometric dimensions but also complex character of form deviations. Simultaneously, reduction of both costs and working time of production process is expected. What is more, shortening of inspection time need to be considered.
The aim of the paper is to present research on the influence of measurement strategy on correctness of cylindricity determination. Recommendations on proper selection of measurement strategy with taking into consideration the birth – cage method, methods of generatrix lines and roundness profiles of elements with different character of cylindricity are displayed.
Presented recommendations allow to use measurement equipment effectively by minimization of measurement time with respect to its metrological correctness.

The paper describes the practical application of thermal error analysis for precision length measurement systems operating in non-ideal environments. Finite element analysis and experimental investigations are carried out to examine the essence of thermal process and to demonstrate the existence and feasibility of the thermal modal analysis in precision line scale calibration system.

The measurement of a part on a coordinate measuring machine may be affected by many factors such as the machine accuracy itself, the measuring environment, the probe configuration, and the measuring strategy. In order to understand the effect of some of those factors on industrial-grade machines, a master production workpiece has been circulated in Brazilian industries for measuring particular GPS features according to a predefined master measuring protocol. Conclusions could be drawn about the behaviour of each machine under varying conditions, the measurement divergences from one similar machine to another operating under distinct conditions, the complexity of measurements with CMMs, and the need for good measurement practices in the productive sector.
