Abstract

PURPOSE:To measure the radius and the center point of an object to be measured with a high precision, by sliding the probe, which has a redius slightly smaller than that of the object, along the face to be measured to magnify and record the movement of the center point of the radius of the probe tip with a high magnification. CONSTITUTION:In case that forms of grooves 2 and 3 of work 1 such as a ball screw having radiuses R1 and R2 are measured and magnified and recorded, contact sphere 5 which has a high degree of perfection of a sphere and has radius (r) slightly smaller than radiuses R1 and R2 of work 1 is fitted to the tip of probe 4 of the form measuring machine. Contact sphere 5 is slided along grooves 2 and 3, and the locus of the center of contact sphere 5 is recorded.
