Abstract

The metrology for quality control is mostly the last step in the traditional manufacturing processes. According to the measuring results, the produced parts are separated into “good” (within tolerance) and “bad” (out of tolerance) parts. The “bad” parts will be treated as a loss of production. Due to many unpredictable factors, some like tool wear, room temperature change, size variation of the row workpiece, and so on, could lead to some parts out of tolerance and many “bad” parts will be produced day by day. This paper will present an innovative method to integrate metrology in the manufacturing processes with smart control systems which could reduce the amount of “bad” parts tremendously. The metrology will be realized in-process, in-situ, or between two process steps. The measuring results will be used as feedback information to correct the command parameters for the control of the process. In such a way, the quality control of the manufacturing process will be carried out in a closed loop. The loss of production could be reduced to the minimum level.
