Abstract
Abstract In this study, for improving the formability and LDR a new method deep drawing with anti-lock braking system (ABS) was developed. The system is based on the blank sliding from the flange into the die cavity continually, which is controlled by the blank holder gap (BHG) and, at the same time by ABS, which moves up and down vertically, conducting anti-lock braking to the blank with the interval of very short time. The experimental results for AI99.8 aluminium sheet showed that higher drawing height and LDR of the cup can be achieved by the use of ABS. It was found that the new system increased surface quality and decreased ear in the top corners of the cup.
