Abstract:
A three dimension computer model full size grading system for processing a shoe model by a triangular geometry mode, said three dimension computer model full size grading system comprising the following steps:(a) a leading processing work: receiving triangular data, performing division of a common member, selecting characteristic lines, filling a grading table and a geometric relation table by a user, and inputting and storing said grading table and said geometric relation table in a data base; (b) a main processing work: inputting gauges of each engineering diagram, selecting each grading item, inputting parameters, automatically reading numbers and dimensions of each size stored in said grading table, reading data of each file and data of stick points of said common member stored in said 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, finding geometric discontinuous positions which are caused by said common member for performing a repair work, and storing results of operation in said data base to respectively mate with positions of respective sizes; (c) a trailing processing work: setting C.A.M. parameters of base sizes, storing said C.A.M. parameters of said base sizes, analyzing geometric members being used by an inner program, deriving geometric members of new sizes from said data base for updating said geometric members of said new sizes, automatically calculating data of dimensions of all sizes for manufacturing a shoe model.
