HARDNESS TESTER AND METHOD FOR HARDNESS TEST

摘要

The hardness tester includes a data obtainer obtaining sample shape data that can specify a shape of a sample; an image capture controller controlling a CCD camera to capture an image of the surface of the sample and obtaining image data of the sample; a matching performer associating the sample shape data obtained by the data obtainer with the image data of the sample obtained by the CCD camera; an indentation former forming an indentation with an indenter in a test position set on the sample shape data after the sample shape data and the image data of the sample have been associated by the matching performer; and a hardness value calculator calculating a hardness value of the sample based on the indentation captured with the CCD camera after the indentation has been formed by the indentation former.

1. A hardness tester for measuring hardness of a sample by forming an indentation in a surface of the sample by loading a predetermined test force on an indenter and measuring a dimension of the indentation, the hardness tester comprising:
a data obtainer configured to obtain sample shape data that can specify a shape of the sample; an image capture controller configured to control an image capturer to capture an image of the surface of the sample and further configured to obtain image data of the sample; a matching performer configured to associate the sample shape data obtained by the data obtainer with the image data of the sample obtained by the image capturer; an indentation former configured to form the indentation with the indenter in a test position set on the sample shape data after the sample shape data and the image data of the sample have been associated by the matching performer; and a hardness value calculator configured to calculate a hardness value of the sample based on the indentation captured with the image capturer after the indentation has been formed by the indentation former.
