Non-Traditional Methods For Making Small Holes

A third process for making small holes is EDM microdrilling. The EDM microdrilling machine is essentially a sinker or ram-type EDM machine with some interesting modifications that enable it to drill holes as small as 0.0002 inch in diameter. Pure tungsten wire is the preferred electrode material for some users because of its exceptional wear ...

Introduction to High Efficiency Milling - In The Loupe

This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure. This strategy differs from traditional or conventional milling, which typically calls for a higher RDOC and lower ADOC. Traditional milling causes heat concentrations in one small portion of the cutting tool, expediting the tool wear process.
