FIELD: measuring technology.
SUBSTANCE: invention relates to measuring technology, in particular for measuring the relative position of planes and an external spherical surface. A base element with two base prisms is placed on the mounting plane. An orienting mechanism with an orienting prism is installed on the base element, ensuring that the bisector plane of the orienting prism is perpendicular to the common bisector plane of the basing prisms. The main reading device is installed on the base element, providing the measuring probe with a predetermined departure relative to the bisector plane of the orienting prism and the location of the axis of the said probe in the common bisector plane. An additional reading device with a measuring tip is installed on the base element, providing the said tip with alignment with the measuring probe and their symmetry relative to the bisector plane of the orienting prism. The measuring probe is removed. The measured object is mounted with cylindrical surfaces on the basing prisms. The measuring probe is brought to the measured object, providing the measuring probe with contact with the measured plane. The measured object is oriented by moving a carriage with an orienting prism to it, achieving the alignment of the working surfaces of the orienting prism to the spherical surface of the measured object and ensuring the displacement of the said object on the basing prisms and the contact of another measured plane with the measuring tip. Readings from the reading devices are taken. The deviations of the distances from the measured planes to the center of the sphere are determined by the indications, and by their half-difference: the deviation from the symmetry of these planes relative to the said center.
EFFECT: increase in measurement accuracy is achieved.
