Research on Accuracy of Automatic System for Casting Measuring

Abstract

Ensuring the required quality of castings is an important part of the production process. The quality control should be carried out in a fast and accurate way. These requirements can be met by the use of an optical measuring system installed on the arm of an industrial robot. In the article a methodology for assessing the quality of robotic measurement system to control certain feature of the casting, based on the analysis of repeatability and reproducibility is presented. It was shown that industrial robots equipped with optical measuring systems have the accuracy allowing their use in the process of dimensional control of castings manufactured by lost-wax process, permanent-mould casting, and pressure die-casting.

Non-destructive testing of automotive heat exchangers

“…Each of these methods enables effective measurement of the research cube and it was considered deliberate to carry out further research in order to search for areas of non-destructive testing methods. The authors [9] pointed out to the legitimacy of using optical measurement systems to control products in automated production and the rightness of development of this field of metrology. In the paper [10] a thermovision and computed tomography for the evaluation of products were discussed.…”

“…The first one provides more information about the material properties of the product but from the point of view of industrial conditions the latter is characterized by greater utility. The works [5][6][7][8][9][10][11] indicate the purposefulness of using non-destructive testing, which application in industrial practice is insufficiently discussed.…”
