METHOD OF ACTIVE TEST OF DIAMETERS Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: measurement controlling system is composed of two converters of linear translations, control unit and auxiliary devices. Positions of crossing of measurement lines of measurement controlling system with working surface of template and with machined surface of blank are checked. Template has cylindrical working surface. During active test coordinate of any check point changes to new value with realization of condition X= , where X is distance between symmetry axis of blank and measurement line of measurement controlling system crossing machined surface in check point; d is specified diameter; h is working range of converter. Method makes it feasible to check positions of two points on working surface of template and of two points on machined surface of blank. Temperature of template is controlled. EFFECT: increased accuracy of test. 3 cl, 2 dwg
