Abstract
Realized measuring with the Renishaw Ballbar QC20-W on industrial robots requires a special approach to measurement and creating of a circular path. In the article, two methods of the circular path creation are compared through experimental measurements. The first method is based on creating a circle using standard program commands in the FANUC programming environment. In the second method, the circular path is created as a polygon that represents the most accurate approximation of a circle required for a Ballbar measurement. The measurement methodology, the analysis of measurement data and results are presented in the article.
Highlights
Trends in increasing production flexibility are one of the reasons for an annual increase in the number of industrial robots in automation [1]
As mentioned in the previous chapters, the Renishaw Ballbar software was used to record the measurement with Renishaw Ballbar measuring device. different errors are identified from the test evaluation, but these are reported in relation to CNC machine tools
In the case of industrial robot measurements, analysis using the harmonics of the profile is used to assess the influence of the CNT parameter on the possible deformation of the circular path and to compare two methods of circular path creation
Summary
Trends in increasing production flexibility are one of the reasons for an annual increase in the number of industrial robots in automation [1]. If the performance criteria measurement is part of the industrial robot monitoring diagnostics in a real production process, it is important that the measurement itself can be conducted in the shortest time and in the simplest way [8, 9]. In this direction, it is possible to use CNC machine tools diagnostics, where the Renishaw Ballbar measuring device is commonly used for quick checks of its performance and to evaluate errors and its sources.
