Study on size effect in mirco cross wedge rolling
This paper introduces a novel microforming process - Micro Cross Wedge Rolling (MCWR) that is very promising in the field of microforming. Numerical simulation has been conducted to investigate the size and dimension accuracy in MCWR. A finiet element model of the MCWR process for manufacturing the stepped axisymmetrical microparts using flat wedge tools has been established utilizing SYS/LS-DYNA. The final diameter in the middle part of the workpiece ranges from 0.9 to 0.6 mm.
