The IDEFO(Integrated Computer Aided Manufacturing DEFinition method) was applied to construct the fuction model of the system, after analysing the data current of the die &mold CAD/CAM system.

Computer aided quality (CAQ) is an important sub-module of computer integrated manufacturing system (CIMS) and the control chart (SPC) is the key technology of CAQ.

In this work an integrated system of computer-aided design and computer-aided manufacturing specifically designed to fabricate affordable transparent face masks is discussed.
