抄録

There are two cases for measuring the roundness of a cylindrical work ; the one for the work with two centre-holes on its sides and the other for the one without the centre-hole. For the former case, setting aside the latter, we are obliged to have a considerable amount of labour for calculation to eliminate the eccentric terms caused by two centre-holes, and so this case is apt to be unavailable. In the present paper, in order to get rid of such inconvenience, the author proposes a new electronical method, and makes it clear that the eccentric effects of two centre-holes are simply eliminated and a precise test of roundness can easily be performed by this method.
