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

1. What is the core process?Subtractive manufacturing involving precise material removal via cutting tools
2. What is the technological advancement?Computer Numerical Control (CNC) enables high automation and complex part creation
3. How did machine shops start?Machine shops started in the 1700s and 1800s when new tools like the screw‑cutting lathe and milling machine were invented, turning hand‑made work into factory‑made parts.
4. What is CNC and why is it important?CNC, or Computer Numerical Control, lets machines follow a computer program to move exactly where they need to, which makes parts faster, more accurate, and less likely to have mistakes.

Subtractive Manufacturing: A manufacturing process where material is removed from a workpiece to achieve a desired form.
CNC Machining: Automated manufacturing using computer-controlled machine tools for precision and efficiency.
Interchangeable Parts: Components manufactured to be identical, allowing for easy assembly and replacement.
Tolerances: The permissible range of variation in a manufactured part's dimensions.
