In 1989 a small group of researchers gathered at Jerusalem, Israel under the sponsorship of CIRP (International Academy for Production Engineering) to address the emerging problem of computer-aided tolerancing (CAT), which is situated prominently at the interface between product design and manufacturing. Since then, such CIRP CAT meetings have been held as working seminars and conferences at an approximate frequency of once in 2 yr.
