Abstract
A three dimension computer model full size grading system is used for processing a shoe model by a triangular geometry mode and includes the following steps: (a) a leading processing work: receiving triangular data for performing division of a common member and selecting characteristic lines, filling a grading table and a geometric relation table by a user, and storing the grading table and the geometric relation table in a data base; (b) a main processing work: inputting gauges of each engineering diagram, selecting each grading item, reading numbers and dimensions of each size stored in the grading table, reading data of each file and data of stick points of the common member stored in the geometric relation table, serially performing a grading operation processing on each geometric file of each size, building constraints in the whole group of triangular geometry to satisfy each grading specification in a local variation manner, and storing results of operation in the data base to respectively mate with positions of respective sizes; (c) a trailing processing work: setting C.A.M. parameters of base sizes, storing the C.A.M. parameters of the base sizes, analyzing geometric member…
