WORKPIECE DIMENSION MEASURING APPARATUS AND WORKPIECE DIMENSION MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a workpiece dimension measuring apparatus and a workpiece dimensional measuring method capable of achieving reduction of operation costs from dimension measurement up to preparation of inspection records after measurement and shortening the operation time while achieving improvement of measuring accuracy, and capable of obtaining also three-dimensional data of flatness, distortion, and so on.;SOLUTION: A workpiece dimension measuring apparatus 1 for measuring the dimensions of a segment W includes: a plurality of measuring instruments 10 each of which includes a multi-joint arm 12 and is capable of obtaining three-dimensional coordinate values by bringing a probe 11 attached to the tip of the arm 12 into contact with the segment W; calibration operation means 21 for performing operation for calibrating a relative position relation between the measuring instruments 10 and operation for automatically calculating the dimensions of the segment W based on respective three-dimensional coordinate values obtained by the plurality of measuring instruments 10; measurement evaluation means 22 for evaluating the dimension measurement results of the segment W based on the calibration result and the operation result from the calibration operation means 21; and data management means 31 for collecting the measurement results from the measurement evaluation means 22 as an inspection record and outputting the inspection record.;COPYRIGHT: (C)2012,JPO&INPIT
