Abstract: A metallic matrix shaping method is provided. A flatness of a plurality of points of the metallic matrix is measured by a shape test device, and a flatness margin of error H between a reference level and the flatness of the metallic matrix is calibrated using the least square method. A controller determines whether the points of the metallic matrix need to be shaped by comparing the flatness margin of error H and a permissive error range K. The controller calibrates a descending distance P by a mathematical formula of P=M+[(H?K)/D]/N+L. A shaping device shapes the metallic matrix according to the descending distance P and a shaping time. The above steps are repeated until the flatness of the metal is within the permissive error range K.

The controller compares the flatness value with a preset value range to determine whether the workpiece is qualified or not. When the workpiece is not qualified, the controller controls the holding assembly to hold the workpiece, and controls the refitting assembly to refit the workpiece.
