Final answer:
CNC machines are better suited for producing complex shapes and high-precision parts, thanks to their advanced automation and consistent accuracy, akin to how technology increases productivity in typing and digging.
Step-by-step explanation:
CNC machines excel in automation and precision, making them better suited than manual machines for certain types of parts. Specifically, CNC machines are exceptionally good at producing:
- Complex shapes: With their advanced programming, CNC machines can easily produce parts with intricate geometries that would be very challenging to replicate manually.
- High-precision parts: CNC machines are capable of maintaining tight tolerances consistently over many items, which is crucial for industries requiring high precision like aerospace and medical devices.
Just like a typist can type more pages per hour with advanced technology or a ditch digger can move more dirt with a backhoe, CNC machines can manufacture more intricate and precise components faster and more reliably than manual machinery.
