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 -
Influence of Workpiece Circumferential Speed in Wire Electrical Discharge Machining
(2013)Procedia CIRP ~ Proceedings of the Seventeenth CIRP Conference on Electro Physical and Chemical Machining (ISEM)In Wire Electrical Discharge Machining (WEDM) a specific wire run-off speed is applied to compensate wear and avoid wire breakage. Since the workpiece generally stays stationary and short discharge durations are applied, the relative displacement between wire and workpiece during one single discharge is very small. In Wire Electrical Discharge Dressing (WEDD), however, the workpiece rotates at very high circumferential speeds, since ...Conference Paper
