Abstract
This invention is directed to an automated measuring device capable of measuring the thickness of essentially any shaped article generally of any materials that is non magnetic. The measuring device of this invention comprises in combination (1) electrical controlling means, (2) magnetic thickness measuring means, (3) mounting means for mounting the article to be measured, (4) computer means for programming the measuring means for measurement of the thickness at predetermined points on the article and (5) means for collecting and recording thickness measurements. Electrical controlling means are employed to control movement of the article to be measured or controlling movement of the magnetic measuring means or a combination of both. The magnetic measuring means comprise a magnetic probe and a magnetic metal ball such that when in a measuring mode, the tip of the magnetic probe is positioned on the side of the article opposite from the magnetic ball and is in magnetic contact through the article. The electrical controlling means may be through digital indexing stepper motors, servo motors or air actuators.
