This paper descries the measuring technology, so-called CAT (Computer Aided Testing) technology which is the most important to design and manufacture of automotive closure parts, such as doors, exhausts systems and its production equipment, to give feedback know-how of operations into the design of product and assembly equipment and leading engineering innovation in manufacturing, and to make use as feedback CAT data for correcting the error margins at other each process, such as CAD, CAE, CAM,. As a result, we could establish the optimal manufacturing system and produce excellent products in quality, delivery, and cost.
