TY - JOUR AU - Marappan , , R. AB - This paper focuses on altering the frictional state in the blank - blank holder interfaces of a cylindrical cup drawing process and studying the resulting effects. The interfaces were tested with both boundary and hydrostatic lubrication regimes and significant changes in draw ratio, thinning and maximum draw force were noticed. Suitable die sets were fabricated to suit a 100 ton double action press and the feasibility of the processes was examined. Finite element simulation of the processes was also conducted and the results were validated. Deep drawing quality low carbon sheet metal blank of 0.7 mm thickness with transversely anisotropic elastic plastic property was used. Keywords: Deep drawing; Blank holding system; Frictional state; Numerical simulation increases LDR. Apart from enhancing the LDR it also limits the variation in wall thickness. Various non conventional deep drawing processes have been developed based on this principle. These processes can be categorized according to the area and mode of altering the frictional state. The area comprises the die region, the punch region and blank holder region and the modes may be boundary, hydrostatic or hydrodynamic. Kasuga et al. / I / formulated the method of pressure lubricated deep drawing.
