METHOD OF CALIBRATING MEASURING HEAD Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: method involves the steps of: placing a measuring head on a device for coordinate measurements through an intermediate rotary unit, determining a coordinate of a tip along one of the coordinate axes of a coordinate system in which the offset vector components of the head tip center from its rotational axis are to be determined by moving a stop till obtaining the signal, rotating the head and determining the tip coordinate along the same coordinate axis again, rotating the head till a full revolution and registering maximum and minimum coordinate values of the tip along the same axis during the full revolution and finally determining deflection vector components of the tip. EFFECT: enhanced accuracy and simplified method. 4 dwg
