What is the effect of surface area on surface roughness in chemical machining?

03 March 2016 1 10K Report

e.g. width of channel increase from 50 micron to 100 micron.

Is surface roughness affects due to increase in width?

Mainly surface roughness is dependence upon the size grain and grain boundaries. If you have to study the effect of surface area you have to take the microstructure of channel before machining.
