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 machine tool function?Specialized lathe for generating accurate screw threads via single-point cutting
2. What is the technological impact?Enabled interchangeable parts and mass production, driving the Industrial Revolution
3. How does the machine make the thread?The lathe has a gear train that links the spinning part (spindle) to a long screw (leadscrew). As the spindle turns, the leadscrew pulls the cutting tool forward at a fixed rate, creating a smooth thread.
4. Why was the screw-cutting lathe so important in history?Before it, making screws was slow and uneven. The lathe let people make many identical screws quickly, which helped build machines and start the Industrial Revolution.

Single-point screw-cutting: A machining process using one cutting tool to create screw threads on a rotating workpiece.
Gear Ratio: The proportional relationship between the rotational speeds of two meshing gears, determining mechanical advantage or speed change.
Interchangeable Parts: Components manufactured to be identical, allowing them to be easily substituted for one another in assembly or repair.
