Shaping method for metallic matrix

摘要

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.

1. A shaping method for a metallic matrix comprising:
measuring a flatness of a plurality of points of the metallic matrix by a shape test device, and calibrating a flatness margin of error H between a reference level and the flatness of the metallic matrix using a least square method; providing a controller electrically connected to the shape test device, and presetting a permissive error range K in the controller, the controller comparing the flatness margin of error H with the permissive error range K, if the flatness margin of error H being within the permissive error range K, the metallic matrix does not need to be shaped, if the flatness margin of error H is out of the permissive error range K, the metallic matrix needs to be shaped; presetting a shaping base level in the controller, the controller determining a first position and a second position by comparing the shaping base level with the reference level, and the first position being coplanar with the shaping base level and the reference level, the second position being non-coplanar with the shaping base level and the reference level; the controller calibrating a descending distance P by a mathematical formula of P=M+[(H−T)/D]/N+L according to material characteristics of the metallic matrix, with P being a descending distance, H being a flatness error, T being a maximum of the permissive error range K, N being a shaping time, L being a compensation of the descending distance P, M being a deformation threshold of the metallic matrix, and D being an each distance increase in an adjusted shaping value for every 1 mm increase in the descending distance P; providing a shaping device electrically connected to the controller, the shaping device having a pivot shaft and a descending shaft, the pivot shaft abutting the first position, and the descending shaft abutting the second position, the descending shaft pressing the second position according to the descending distance P to realize the shaping; and repeating until the flatness margin of error H of the metallic matrix is within the permissive error range K.
