Super-finished Surfaces using meso-micro EDM
(2013)Procedia CIRP ~ Proceedings of the Seventeenth CIRP Conference on Electro Physical and Chemical Machining (ISEM)A novel stochastic orbiting strategy combined with extremely low stray capacitance sinking EDM machine offers the capability to achieve super-finished surfaces (Ra <0.1 μm) without pre-polishing of the copper tool electrodes. Surface defects such as inhomogeneity, cracks, arc spots and black spots have been analysed and reduced, while improving material removal rate with lower tool wear. Super-finished surfaces thus generated have uniform ...Conference Paper
