1. What was Machinist's job?Operates and programs machine tools for precision manufacturing
2. What is the technical expertise?Proficiency in blueprint interpretation, GD&T, metrology, and material science
3. What is the technological integration?Expertise in CNC programming (G-code) and CAM software
4. How did machinists change over time?They began by shaping metal by hand, then used powered machines during the Industrial Revolution, and now use computer programs to run machines.
5. Why do machinists need to measure so carefully?Small mistakes can cause big problems in things like airplanes or medicine, so machinists use tools that can see differences smaller than a thousandth of an inch.

Machine Tools: Automated or semi-automated machinery used for shaping materials through cutting, grinding, or other processes.
Blueprint: A detailed technical drawing specifying dimensions, tolerances, materials, and finishing requirements for a manufactured part.
CNC (Computer Numerical Control): A manufacturing process where pre-programmed computer software dictates the movement and operation of machine tools.
