this study was conducted to determine the use of three-dimensional ultrasonography (3du) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3du of the eyes were done using a 5–12 mhz linear trapezoid transducer. 3du of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

This paper presents the achievement of a China NSFC project. A technique to calibrate laser tracker using CMM has been developed. A laser tracker with working range of 35m can be calibrated accurately and quickly using a CMM with working range of 1m. Studies have shown that angular errors are the key contributor to measuring errors of laser tracker. A device to measure angular errors of laser t...

The press shop at BMW‘s Dingolfing plant relies on optical metrology systems including automation and standardization for inspection of sheet metal components. Here, 3D coordinate measuring technology from GOM sets completely new standards, offering high time-saving potential since sensor, automation and inspection software all come from a single-source provider. The automation processes in par...

The paper presents the results of contact and non-contact measurements of external profiles of selected grinding pins. The measurements were conducted in order to choose the appropriate measuring technique in the case of the considered measurement task. In the case of contact measurements the coordinate measuring machine ACCURA II was applied. The used coordinate measuring machine was equipped ...

The validation of the conformity parts according to ISO 98-4 standard, cannot be achieved without an accurate estimation measurement uncertainty, which can become difficult when it comes a complex strategy control geometrical specification mechanical part using Coordinate Measuring Machine (CMM). purpose study in this paper is analyze following Geometric Product Specification (GPS) Standard, es...
