ANALYSIS METHOD FOR FORMABILITY OF FORGING PROCESS AND MEDIUM RECORDED WITH ITS PRACTICE PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an analysis method for a formed body of forging process capable of applying whether a cross section slightly changing a cross sectional area before/after working can be set or not and visually grasping/discriminating whether its formability is normal or abnormal and to provide a medium recorded with its practice program. ;SOLUTION: A three dimensional model of a preceding process and a succeeding process is prepared (#1), its surface shape is picked up (#2), these surfaces are arranged up/down (#3). By sliding these, an overlapped part is generated (#4). The overlapped part of both surface shapes generated by sliding is image displayed (#5). Based on the state of the generated overlapped part and its spreading, the normal/abnormal decision of workability in term of stability of placing and formability is grasped/discriminated (#6). Further, the transfer level helpful for a process design can be found.;COPYRIGHT: (C)2000,JPO
