Die-Less Rapid Prototyping Process: Parametric Investigations

摘要

High flexibility of die-less rapid prototyping (DLRP) process imposes its' use for fabrication of sheetmetal components. However, due to the slowness of the process it is not extensively used in industries. In order to increase its suitability for the industries in-depth study is essentially required. In the present investigations effect of various process parameters like feed rate, rotational speed of the tool and incremental depth on DLRP process is carried out. Frustum of cone with 80° cone angle are formed. The material used is Al 1200-H14 aluminum alloy. The forming tool is having hemispherical end. Effects of these process parameters on feasibility of forming, forming time, geometrical accuracy, and surface quality of formed surfaces are investigated and reported.
