The impeller blades are very important and precise parts in turbine, but they can be worn and deformed easily. In this paper, we present a novel approach to detect the shape of the impeller blades. The proposed approach is to compare the designed 3D model of the impeller blades with the virtual 3D model of the tested part which is reconstructed by non-contact coordinate measuring machine. The n...

Injection molding process is one of the most important methods of forming in the plastics manufacturing industry. Shrinkage and out of roundness are phenomenons that affect the final product quality. In this study, the effect of the thickness of cylindrical parts from polypropylene material on shrinkage and out of roundness has been investigated. For this purpose, injection molding process is s...

Accurately manufactured gears require a reliable, holistic, and fast inspection method. Standardised geometrical parameters enable consistent regulated of gears; however, current methods include only limited set measurements for at specific locations. Therefore, method to obtain holistic three-dimensional (3D) with an optical was thoroughly investigated. The measurement data were acquired via 3...

nowadays cmm machines are widely used in surface measurement and inspection. as inspection results from cmm machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). however, cmm machines give more reliable and accurate results rather than non-contact methods but also these results come with error when ...

This paper studied the key technologies of 3D surface measurement system based on linear structured light vision sensor, and effectively achieve the integrity measurement of curved surface. The establishment of the line structure light 3D surface vision measurement system with three coordinate measuring machine for motor drive and control device, effectively with high precision motion measureme...
