Description

Measuring device and measuring method {MEASURING APPARATUS AND MEASURING METHOD}

The present invention relates to a measuring device and a measuring method with improved reliability.

It should be noted that the contents described in this section merely provide background information about the present invention and do not constitute the prior art.

When developing bridal products using steel materials, a wide variety of parts processing methods are applied. The most typical processing methods are press processing or stamping processing.

Of these, the most problematic problem in press processing is whether a desired shape can be obtained without breaking the material.

The moldability of the material can be largely classified into four types: deep drawability, stretchability, bending workability and stretch flangeability, but in the actual press working, the above moldability is complicatedly combined.

As a result, it is difficult to predict the complex stress state that is received during press processing only by the yield strength, tensile strength, and elongation, which are the values of the uniaxial tensile force evaluated in the tensile test.

Therefore, the need to evaluate formability through laboratory tests in the method most similar to the actual conditions of use of the material emerged, and in the 1960s, the concept of Forming Limit Diagram (FLD) was introduced by Keeler and Goodwin.

Since then, the Circular Grid Analysis (CGA) has been introduced, and it has been recognized as the most common method for evaluating the formability of materials with the FLD concept by Keeler and Goodwin.

The molding limit chart evaluates the formability of the material in the plate state by evaluating the formability for each deformation mode that the material can receive for the lack of material properties that can be obtained by uniaxial tension.

The shaping limit is generally measured by a method of determining the strain by measuring the entire specimen with a strain mode and a corresponding point strain camera in a plate state.

At this time, if the strain is measured by the whole point measuring method, the distance between the specimen and the camera for measurement and the focal state, the specimen for measuring the entire specimen image, and the rotation of the molding limit due to the occurrence of the unmeasured part when manually rotating the specimen There is a problem.
