Electrical Discharge Machining of Micro Holes on Titanium Sheets
Volume 7: 5th International Conference on Micro- and Nanosystems; 8th International Conference on Design and Design Education; 21st Reliability, Stress Analysis, and Failure Prevention Conference, 2011Micro-Electrical Discharge Machining (μEDM) has become a widely accepted non-traditional material removal process for micro-manufacture of conductive materials considered difficult to be cut using traditional machining technologies. Moreover, EDM is an ideal process for obtaining burr-free micron-size apertures with high aspect ratios. Aim of this work

Casting of array micro-holes on Al components
The International Journal of Advanced Manufacturing Technology, 2015A novel preparation process of array micro-holes on Al components is proposed. Carbon fibers were chosen as the hole cores in order to prepare array micro-holes in the casting method. Aiming at demonstrating the quality of array micro-holes, the roughness (R a ) of array micro-holes is ...

Vibration Drilling the 0Cr18Ni9Ti Stainless Steel Micro-Hole
Applied Mechanics and Materials, 2012Austenite 0Cr18Ni9Ti stainless steel is one of difficult-to-cut materials. It has poor dilling process, especially for micro-hole machining. The main reasons are the tiny drill, poor rigidity, easy to deviation. Moreover, the chip is difficult to discharge, so the drilling force is increased and the drill bit is easy to break, or even it is impossible ...
