Abstract
A method for inspecting engravings in a tire mold includes inputting in advance into a data processing device two-dimensional image master data of an engraving formed on a surface of a side plate in a plan view using basic data set as a reference, the image master data having a radial component and a radial position of the engraving corrected on the basis of a locus length in a radial direction of the surface of the side plate; generating two-dimensional image actual measurement data, the image actual measurement data having a radial component and a radial position of three-dimensional data acquired via actual measurement corrected on the basis of a radial locus length of a surface of a side plate on which actual measurement was performed; and determining whether or not an image shape and an image position of the image actual measurement data is within a tolerable range.
