CALCULATION METHOD OF STRAIGHTNESS ERROR AND CORRECTION METHOD OF MEASURED VALUE IN DETECTOR FEED DIRECTION OF ROTATION-DIRECT-ACTING FUNCTION TYPE CIRCULARITY MEASUREMENT MACHINE

摘要

PURPOSE: To reduce manday, lessen the dispersion in precision for every kind of machines without any need of manual operation performed by a skilled worker, easily perform maintenance and inexpensively realize the measurement of a straightness error correction quantity in the feed direction of a detector of a rotation-direct-acting function type circularity measurement machine. ;CONSTITUTION: Direct-acting measurement of a side face of a straightness check gage is performed and obtained data are stored as first data in the calculation method of straightness errors in the direction of feed along the column of a detector of a rotation-direct-acting function type straightness measurement machine for measuring the circularity of each cross section of a work. A straightness check gage is rotated by only 180° around the shaft center, the direct-acting measurement of the same face of the straightness check gage is performed by the use of a detector and the obtained data are stored as second data for the purpose of making a straightness error correction quantity of a difference between the first and second data.;COPYRIGHT: (C)1993,JPO&Japio
