TIRE MOLD MEMBER INSPECTION METHOD, TIRE MOLD MEMBER INSPECTION SYSTEM, AND INSPECTION METHOD FOR MOLD MEMBER MANUFACTURING PROCESS ACCURACY

摘要

PROBLEM TO BE SOLVED: To perform an inspection of the shape accuracy of a tire manufacturing mold member over the member as a whole, including parts other than a surface corresponding to tire surface.;SOLUTION: By comparing mold member three-dimensional measured data acquired by measurement with the three-dimensional design data of the mold member, the amount of deviation of the shape of the manufactured mold member from the three-dimensional design data is derived. The mold member corresponds to one of partial shapes obtained, by dividing a tread surface shape over one round of a tire into a plurality of parts in the tire circumferential direction. Based on the comparison, a measured data reference point in the mold member three-dimensional measured data is set, according to the acquired mold member three-dimensional measured data, and the measured data reference point and a design data reference point are made to coincide with each other, and the amount of deviation of the three-dimensional measured data from the three-dimensional design data is derived.;COPYRIGHT: (C)2008,JPO&INPIT
