Final answer :

Pre Machining involves removing some extended micro rough areas from the workpiece that are undesirable for advanced manufacturing processes.

<h3>What is pre-machining? What three different machining processes are there?</h3>

Roughing operations are used to quickly remove huge amounts of material and create parts with geometry that closely resembles the desired shape. Following roughing, a finishing procedure is utilised to get the desired final geometry and surface finish.

Turning, drilling, and milling are the three main machining operations. Shape-changing, planing, drilling, broaching, and sawing are additional processes that fall under the umbrella term "other operations."

Explanation :

Because of its superior surface smoothness and low dimensional inaccuracy, pre-machining is essentially beneficial and desirable for any advanced manufacturing processes.

For instance:

If pre-shaping is not done in EDM (Electric discharge machining), there may be chances of arcing in the material removal zone. Hence that results in inaccurately measured dimensions.

Hello. I believe you are referring to the role of NGOs in women's empowerment.

NGOs are organizations that promote aid to social minorities that are undervalued and ignored by society. Among these minorities, women, form a very comprehensive minority that is often devalued, exploited and even abused in different parts of the world. However, there are NGOs that are committed to not only helping these women, but to empowering them. Many NGOs provide vocational courses for women, so that they achieve financial independence. In addition, there are NGOs that provide legal support against cases of violence against women, in addition to promoting awareness of women's rights, academic advancement, training and economic assistance. All of this has a very significant role in the lives of women, giving them the support they need to shape their lives in the way they believe is right.

Julli [10]

Answer:

This is not plagiarism

Explanation:

In research, the term plagiarism refers to the fact of taking someone else's ideas or concepts and use them as if they were one's own. In other words, when writing a paper, we use someone else's work and we don't quote the original authors and it seems as if the words were ours.

In this example, <u>the student quoted the original author of the paper and used one of his quotes in his work but he did give the author credit and he didn't make it seem as if the words were the student's own words. </u>Therefore, this doesn't classify as plagiarism.
