Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary mechanism?Material removal through shearing action of a rotating cutting tool
2. What is the key variables?Material properties, tool geometry, rotational speed (RPM), and feed rate
3. What is hole drilling?Hole drilling is a process that removes material by rotating a cutting tool called a drill bit. The bit cuts away chips and makes a hole.
4. Why do drill bits have flutes?Flutes are grooves that help pull the chips out of the hole so the drill can keep working smoothly.

Subtractive Manufacturing: A process where material is removed from a workpiece to create a desired shape.
Feed Rate: The speed at which a drill bit advances into the material being drilled.
CNC Machining: Computer Numerical Control; automated manufacturing processes guided by computer programs for high precision.
