Abstract: Incremental forming process of a face-part is discussed. The procedures include modeling based on UG software and problem between it, how to make die and get tool path code, how to get tool path code which can be used in positive incremental forming and tool path’s information. The face-part of high quality is formed successfully. The result is that complicated sheet metal part can be manufactured successfully based on positive incremental forming at reduced cost and processing time; UG software can not give required tool path in order to manufacture complicated parts by positive incremental forming. Auxiliary software is needed to serve the purpose. The accuracy of the part thickness in accordance with angle depends upon the precision of tool positioning. The thickness distribution along the part obeys the law and designing part can be manufactured successfully when tool positioning is high. Thickness between tool and blank becomes thinning smartly when tool positioning is low so the part will become failure abnormally.
