Investigations on Incremental Forming of Low Carbon Steel Sheets
Low carbon steel sheets are used invariably in automobile body panels and construction structural applications. Conventional forming techniques require forming dies and heavy duty presses to make required shapes, which are costly in manufacturing. Incremental forming is a recently developing die less sheet metal part production technique in which the necessary part is obtained by gradually tracing its contours on a sheet of required thickness using stepwise tool indents. In this investigation, Low carbon steel sheets of different thicknesses were incrementally formed using a hemispherical tool under varying step depths. The final thickness of the sheet, forming angle, roughness and microhardness of the formed shapes were characterized. The microstructure of the formed materials was studied using optical microscope.
