Comparison of Selected Methods of Probe Radius Correction Based on Measurements of Ceramic Workpieces

The article concerns the analysis of results of coordinate measurements of ceramic products. The measured parts were made of ZrO2 based ceramic material and machined using the CNC machine tool Ultrasonic 20 linear. The analysis of results of measurements of ceramic workpieces concerned the comparison of corrected measured points obtained by means of different algorithms of the probe radius correction process. The first algorithm was developed based on the Lagrange interpolation method of indicated measured points. The second method was the commercial one and it is available in the Calypso software which can cooperate with a coordinate measuring machine.
