In this paper the relation between the static characteristics and the size of cantilever onecomponent dynamometer using the structure of parallel beams for grinding is analyzed by FEM. The results are useful of the design and the manufacturing of this dynamometer. The performance of this dynamometer is evaluated by the output strain per unit displacement at the loading point as follows : (1) The performance of this dynamometer is improved if the distance between parallel beams is larger or the length of parallel beams and the length of the dynamometer are smaller. The performance is the greatest when the thickness of a parallel beam is about 20 % of that of the dynamometer. (2) The performance is not hardly affected by the decrease in size accuracy. The influence of the manufacturing error of the square hole is small. (3) The interaction caused by the size error is negligible, but it is better that the double beams should be parallel.
