The surface shape is judged visually! "Gauge for checking fit / model"

[Concern] I want to confirm the hit.

<Checking the Fit> The term "fit" refers to the degree of conformity when two surfaces (one primarily convex and the other concave) come into contact. In other words, it pertains to how precisely the "taiyaki maker" and "taiyaki" align with each other. <Why It Needs to Be Checked> There are various reasons for this. For example, when two paired objects slide against each other, having a good fit leads to smoother movement and eliminates vibrations or noise. It also prevents uneven wear since only specific areas do not rub against each other. <How to Check> Apply a thin layer of a marking paste (red paste) or blue paste to the reference surface. Press the item being inspected against the area where the marking paste has been applied and check how much of the paste transfers to the item. If the shapes match, the marking paste will transfer uniformly; if there are differences in shape, only parts will make contact, resulting in partial transfer of the paste. <Common Inquiries> Most inquiries are about checking the fit of shapes such as spherical or tapered convex and concave forms. The typical application is to verify whether the shape of mass-produced products aligns with the established reference.
