2. Explain with neat sketch of “Etching” the surface finishing process.( Minimum 1 and half pages including diagram.)
1) Identify what are the step by step machining
and grinding processes to produce that part
from a blank material. Assume that both part
made from cast iron.
2) Then, taking into consideration of green
manufacturing/ sustainability, you need to
suggest what kind of improvement that you
could do to the list of machining processes that
you have identified (e.g. change of machining
operation, use of dry machining instead of
using cutting fluid or etc.) to reduce power
consumption during machining, reduce waste
and even pollution. Please give justification on
your suggestions.
3). You need to include the figure of your
chosen part and label the processes involve.
Discussion :
a. Define by what is meant by metallography
b. What is the difference between metallography and metallurgy?
c. Why must we avoid an increase in temperature in the specimens?
d. Why must we rotate the specimen 90° each time between
polishing phases.
e. How can we avoid the oxidation of the specimen's surface while
treating it with etching solution?
f. Explain how the etchant solution shows the grains and grain
boundary
g. Why is the grain boundaries oxidization more sever and are the 1st
to be oxidized than the grain surface themselves?
