Can anyone suggest to me the preferred method for obtaining surface roughness of a microhole i.e., should I drill the microhole first and then cut it into 2 pieces OR
drill the microhole at the common line of touch between the 2 pieces kept adjacent to each other.
Dear Shivraj : Sorry, but I do not understand the question ....
When you say "method to "obtain" surface roughness", you are referring to create roughness or to measure the roughness?
I will answer considering what you want to measure the microhole roughness.
What is the reason that motivates your question? The problem is because the instrument that tyou intend to use, can´t measure the Microhole roughness directly?
Which method you intend to apply for measuring roughness? Stylus profiler, AFM, Optical Profiler, other? What roughness intend to study : the bottom, walls or both ?
Some times, the use of surface replication using commercial products, for example we have used some times, fast curing two-part silicone rubber compund, to create high resolution replicas of microstructure or 3D structures.
We use this option in various circumstances such as when the surfaces are in very deep positions, in which the profiler stylus can´t reach the interest surface, or when the light reflected by the optical profiler is weak, or when the surface to be measure is transparent , when is difficult or impossible the access to the surface due instrument or sample limitations, the replication can be a good choice.
Good luck with your research
Thank you......@Carmen Serra-Rodríguez for your guidance.
Thanks @Eraldo Banovac I will definitely go through the paper suggested by you.
I would like to add some more information to my question.
We are interested in knowing the surface roughness of 0.1 mm microhole drilled through microdrilling. We want to use AFM/SEM for obtaining it.
What I want to ask here, Is it ok to first drill the hole and then make it open by cutting it into 2 pieces OR should i places 2 workpieces side by side and drill the hole at the common face?
