Abstract
A non-transferred arc plasma torch has been used as a controllable heat source to produce internal stress in sheet metals, causing plastic deformation without the necessity of hard tooling. This method has the potential to reduce development cost and lead time for forming sheet metal prototype parts. Experimental work using a robotic system has been performed on 0.8 mm thick sheets of Type 304 stainless steel and of low carbon (mild) steel. The effects of various process parameters on the obtained shape changes and on the resulting material microstructures has been studied. Data is presented for the development of simple linear bends in the two materials as a function of the process parameters which directly affect the rate of heat input.
