Description 649-657
Sheet hydroforming with female die process (SHF-D) is easily applicable without controlling of pressure and blank holder
force paths compared to the hydroforming with punch process. Shallow parts can be produced easily with using SHF-D process
which is used a lower cost production method in a wide variety of sectors. Limiting drawing ratio (LDR) is indication of
formability of sheet metals is determined by using cylindrical punch die. In this study, for the first time, the LDRs of the SS 304
material with different thicknesses was determined experimentally by using the SHF-D instead of sheet hydroforming with
punch unlike in the literature. FEA of SHF-D process has been performed. The results showed that relatively shallow sheet
metal parts can be easily produced without there is no need to be optimizethe pressure and blank holder force paths by means of
SHF-D using obtained LDR. It is important to know the forming limit in the SHF-D, since it can be a more economical
production method, especially in the manufacture of shallow and large parts used in the automotive and aerospace industries
and obtain more quality products than that from classical deep drawing process. By knowing these ratios, die design and parts
manufacturing can be realized less costly. The LDR was experimentally obtained as 1.82 with using the SHF-Dfor the SS 304.
The FEA results are in good agreement with experimental results. So, it is useful to analyze the FEA before designing the dies
that will be used with the SHF-D.
