Outline of Final Research Achievements

We proposed a forming method of resin sheet which use incremental forming. Incremental forming method is practically used as a method of RP/RM method of metal plate. In this forming method, thermoplastic resin sheet was softened by heating, and softened resin was pressed discretely, finally objective shape by accumulated deformation is obtained. Temperature control for keeping resin in formable temperature is difficult, due to the resin has narrow temperature range from begin soften to melt down.
In this study, knowledge was obtained about the material degradation during processing, and formable temperature range by preliminary experiments. The forming system which can heating locally only processing point, and performs the molding while maintaining the target temperature by feedback control was developed. As a result, it is possible to suppression of crack and sagging of the sample due to overheating by the application of local heating.
