“…Raster scales of wide range of accuracy and dimensions, system of graduation: 360°; 2 n ; 10 n number of strokes in the circle, various coded scales, etc. are used for special tasks of instrumentation and automatization [7,8]. So, measurement of every kind of such various graduation systems must be ensured on modern angular comparator.…”

“…These assumptions can help in determination of mechatronic impact on the information -measuring system for the elimination of systematic errors. A case of scale errors correction is presented in [7,8]. Piezoplates and simplified bodies from piezomaterial were applied for micrometric displacement for correction of the systematic errors of the raster scale.…”

Analysis of measurement system as the mechatronics systemTo cite this article: V Giniotis et al 2010 J. Phys.: Conf. Ser AbstractThe paper deals with the mechatronic arrangement for angle measuring system application. The objects to be measured are the circular raster scales, rotary encoders and coded scales. The task of the measuring system is to determine the bias of angle measuring standard as the circular scale and to use the results for the error correction and accuracy improvement of metal cutting machines, coordinate measuring machines, robots, etc. The technical solutions are given with the application of active materials for smart piezoactuators implemented into the several positions of angular measuring equipment. Mechatronic measuring system is analysed as complex integrated system and some of its elements can be used as separate units. All these functional elements are described and commented in the paper with the diagrams and graphs of errors and examples of microdisplacement devices using the mechatronic elements.
